The other idea I rather liked was something like the rectangular shape of your first (above) mock-up. The differences would be I would install a pivot point at the bottom of each of the four legs. Then a winch can lower it down to the deck. I have seen it done with snow machines and it was brilliant. It would not not be too dissimilar to this. https://www.dock-factory.com/product-page/boat-lifts

Thank you Phoenix2013, it should be pretty swell once we are complete. My though for the motorcycle rack is more along these lines. The rails do do not need to super tall, as the rack only need go half the height of the rack of course. Thank you for your help. That all makes great sense. Well explained. Thank you.

On the ReGen. I have a D13 and it took Four full forced ReGens to get the computer happy after I replaced the nox sensors and cleaned the filter last month. I am no expert but I am given to understand that this is not entirely uncommon. Good of luck with the rest of the issues.

(I cut a bit out of the middle to save space. I’m sure folks can look above if they wish to reread your thoughts. Cheers) I hope you had a great ride! Thanks for the info. Yes, I am tracking all of that. I had done my maths on lengths and I am comfortable with where I will sit length wise. Now I am to the point of determining balances and weights. As I mentioned I have listed as many of the weights as I now have, and I can gather the rest in due course. Alaska Law, “the overall length of a combination of vehicles, consisting of a truck and one cargo-carrying vehicle or a truck tractor and one or two cargo- carrying vehicles, may not exceed 75 feet;” -17 AAC 25.012.d3 (Edit: I should add, for those who may not like the wording, that is just how we do it in AK. The law calls side by sides, three wheelers, and four wheelers, 6x6 and all other off highway vehicles with more than two tires “snow machines” and we all get snow machine registrations go figure.) I have been told (above) that there is not reciprocity on length laws from state to state. I was not aware of that, and will certainly research to confirm, but for now I will operate as considering it fact. The length of my vehicle and trailer as sketched out is well within that limit. I can hang off a nice bicycle rack on the back of the trailer should I care to. Thank you all for the concern on my length and cost. Has anyone any more thoughts on the topic which we were kindly initially discussing? by the way noteven. I was meaning to ask, fancy a trip to Idaho? I’ve got a pad of paper waiting. LOL 😂. Take care, and God Bless.

Thank you Jack, that is a lot to digest. To answer your questions, perhaps out of order: I can buy an all metal car hauler flat bed twin axle style trailer without the axles and without the tongue for $3k. I’ve already sourced it from a well known and reputable trailer builder. Ultimately then it comes to mounting it to the truck. ~$500.00. It really is not that big of a feat. The lift I am not trying to do right away, but I have my ideas. I have a great deal of experience in the expedition travel or vehicle based world travel arena. In this world we have seen motorcycle racks for over a dozen years. It is actually fairly straight forward. Your rack required significant engineering because of the width I should assume. I have never seen how it is raised or lowered and that may make a difference as well. I have seen people putting two spare tires the size of two HDT tires with heavy off-road tread side by side, and then a 450lbs motorcycle beyond that. It can all be made to be lifted on rails by a simple warm winch. Pins to lock it in place once up. Again, it is fairly straightforward. I am not at all trying to crowdsource anything, though I know someone who did it fairly successfully with a massive expedition truck. I am simply attempyto crowdsource the calculations. I respect the experience of those here. I would be remiss not to utilize the experience I already have. I realize that a 30,000lbs truck going down the highways and down bouncy 4x4 trails is not the same as a 25,000lbs truck just built for highway use, but I believe the similarities exist in substantial enough areas as to continue to use both your wisdom and mine. My thought for the eventual deck is either a slide system that goes vertical or a hinges system that flows from BOC towards the rear of the truck. Edit: Jack I forgot to answer your question of placement. Sorry about that. Right now I do not have the Jeep, we only had an RZR. The RZR is ~60” wide. That gives me 21” on either side of the machine with which to utilize as motorcycle parking. I will park the bikes first and strap them down. Then I can park the RZR and strap it down. When the Jeep comes along it will be fully 13.8” wider, and will require some rethinking of the configurations. Either way, with largest, by far, bike that is only 20” wide (not including the handlebars) I should easily be able to park the bike at the outer edge of the deck and have room to park the RZR. I hope this has answered some some of your questions. God Bless, Brian

Thank you for your intent. I would appreciate your thoughts. One of my concerns is, in fact, having an over hang that is too long or too short. Too long, obviously, as I am sure you will point out, will unload the front axle and provide very scary and unsafe conditions. By too short I mean that it would limit my turning angle significantly, and while I want it as far back as needed to be safe, I’d rather not go al the way back when it is not needed. I hope that makes sense. The motorcycle, I plan to park the Jeep either to one side allowing access for bikes up the other side, or preferably the Jeep in the canter with the bikes on either side. Lastly I have considered putting a shelf above the hood of the Jeep, to hold the bikes. Not unlike the rack RVHLifestyles recently built to hold a pair of spider trikes. I should mention one bike is an adult dirt bike, and three children’s bikes. Anyhow, thank you for your time. Brian

Thank you Rick, I am aware of it and I have read through it multiple times. I am simply trying to gain information on how to calculate the weight and balances. I know I will need to get the weights I just don’t know how to plug them in to insure my truck is safe. I appreciate any any advice offered in kindness. Regards,

HAHAHAHA! So true. But just so funny the way you wrote it. Sorry. Just got a real kick out of it. Awesome.

Thank you everyone. I cant believe I failed to say that it is in fact a tandem truck. Apologies. On the length, I have yet to see nor had anyone show me where there is a length limit on an HDT towing. The only thing even remotely applicable is that the truck can be any length you like and the trailer can not exceed 53’ in most states. So I am none too worried about that. Thanks for your concern though folks. I don’t disagree with the pen and paper idea, but my brain simply does not work that way. I think I grasp the explanations, and I understood the lever & fulcrum concepts. But I fail to grasp how I might determine the center of the weight on the Jeep to know how that works in, and I seem to be at a total loss for how I’d know the weight of the bed. I guess I would have to speak with the bed builder and get his thoughts. A big thing right now that is eating at me is “will I need to relocate the axles or not, and if so how far, and what will that do to my turning radius?” If I felt comfortable at least with that i fo I could take it to the frame folks and get them going on the stretch, hitch removals and new hitch mount, and possible axle relocation. I wish I could just find a one stop shop similar to RVH but for about a third the price. I recon the folks I have worked out can do it for significantly less than even that, but for such I have to do the math and tell them what to do, and it is on me if I screw up. Sadly all of the folks around here who could do it won’t because it is not for a commercial application. How weird is that, right? Sigh. Below are the measurements I believe you are asking for, at least what I have now. If I am missing something let me know. Wheel base to center of tandems 230” BOC to second axle 5’6” (66”) BOC to third axle 9’9” (117”) Average, or BOC to midpoint between tandems 7’7.5” (91.5”) BOC to end of frame rails (including slope) 12’3” (147”) Hope that makes sense. Please let me know if I appear to have made any blatantly obvious errors. LOL Thanks again, Brian

Revoking titles, that is harsh. Now it seems the OP was having a hard time showing or convincing Texas that the truck met the standards. SD requires only an affidavit from you stating that you did the conversion and they will send the title out. Once titled it is easy to then transfer that title to your state and get plated. My state is spectacular about converted trucks, but I would have to bring it all the way back before they would ok it. Well that is great when I can’t drive it without a plate. So SD was, for me, a clear choice.

Hello all. BLUF (Bottom Line Up Front) I need the mathematical formula to be sure the bed build and the toys on the bed/hitch/fifth wheel pin weight do not unload the front axle too much. (Thus requiring me to move the tandem axles, which I am ok with, but don’t want to unnecessarily.) I recently purchased a Volvo truck and I need to stretch the frame about eight to nine feet to put a vehicle and some motorcycles lengthwise on the truck, and still pull our 5er Truck is a 2013 volvo VNL64T730 D13 ishift with a 230” wheelbase. We plan to put a 14’ two door Jeep, under ~4000lbs, ~1000lbs of motorcycles, 3k pin weight and a 400lbs hitch, not including the extra frame and the bed itself. I have no idea at all how to figure this out, and I really do not want to make the truck unsafe. The nearest Volvo dealer will stretch the frame and mount the hitch, and a local trailer and flatbed company is going to build the bed and install it I am planning to dovetail the end of that matters at all Thank you much! Brian

Chad can you put me on the email list for the photos? I am still a bit disappointed that we were called away at the last moment. Thank you

Thank you Randy, hopefully I can get it worked out soon and start a build.

There was a bar called The Library near my first university, and they would always play this as the last song. What a crack up to run into it again.

Randy I believe I have seen yours, blue Kenworth/Peterbilt style truck with a low roof? Thank you for the idea of the photo. I never thought of that. Hero, I did do that, thank you though Thank you everyone! I really appreciate your help. Brian
