phoenix2013 Posted June 29, 2023 Author Report Share Posted June 29, 2023 Getting philosophical. It has been a decade or more since I designed and had a bed fabricated. Got reminded what a gas it is to first conceptualize it on paper really get into it and then see it become a reality. We are closing in on it.

Sculptor Posted June 29, 2023 Report Share Posted June 29, 2023 I was rereading this post this morning. In reference to your truck frame troubles, where the frame often doesn’t “stay put” from the factory. IE the warps and pregnancy bulge you mentioned. Would a large scale white light scan of the truck frame and suspension be of use to identify the frame ramblings beforehand? I’ve conveniently set aside any guesses on cost or availability of a scanner. We stopped at a park in MT last summer and there I met a techie who specializes in CAD work for the local refinery. He scanned the back end of my truck just as a favor. I have no software that deals with that flavor of 3D file, but he gave me some polygons that are close enough, in case I ever get the urge to design a bed. (Full disclosure; I can push buttons but “design a bed” gives me way more status than I deserve. 🤓) Quote Kevin and June 2013 Volvo VNL 730 D13 Eco-Torque @ 425 Ratio 2.47 2014 DRV 36TKSB3 Link to comment Share on other sites More sharing options...
phoenix2013 Posted June 29, 2023 Author Report Share Posted June 29, 2023 (edited) We were remeasuring the deck with the welder yesterday for the rear panels. New "discovery", the ET is not in the center, right side is 3/4 of an inch wider than the left side. Scanning software certainly would have shown this but those programs and equipment are still in the stratosphere cost wise. So, you have to expect those kind of surprises and deal with it.

rickeieio Posted June 29, 2023 Report Share Posted June 29, 2023 When I was doing the final assembly before paint, I found that the entire rear of our bed was off center by 3/8". I could either redo all my mounting points, or simply shim my toolbox mounts and live with it. It still bugs me.

phoenix2013 Posted July 4, 2023 Author Report Share Posted July 4, 2023 Got couple of ideas banging in my head, have some leftover parts from yonder years of bed building. Hate to let them languish when there is a bed where we can affix them. Want to wager some guesses where this brain fart is going. Quote Link to comment Share on other sites More sharing options...

Wrknrvr Posted July 5, 2023 Report Share Posted July 5, 2023 Henry, This only a suggestion. Looking at the bed in the current production stage, I have a different thought. Looking at the space from behind the rear wheels to the rear bumper. That is a lot of cubic feet of storage, that is just sitting there. If that area was utilized, not only could it contain the ramps, but there could be more storage space, just for the taking. If the side panels were built to accommodate that space, from the rear wheel to the rear bumper.? The storage area from the frame rail to the outside of the bed could give considerably more storage space. With the proper doors for access. It would also control road debris from flying up there. With a short mud flap on the front of the storage bin. Just saying Quote Link to comment Share on other sites More sharing options...

We had so much space under there with this truck that we decided we have to mount something under there. I've done three trucks with under frame stuff, water tanks, ramps storage and pull out drawer similar to this one. This one has given me conniptions, bathroom trip didn't help. I think I got it nailed this morning, I'll post the solution. The challenges were: the doors, drawer clearances, drawer stops, wheel rails, rails mounting and few other things.

Not a thing of beauty but the overall length, wheelbase, tire size, location and differential height are dead on. Want to see the break-over clearance situation.

phoenix2013 Posted July 5, 2023 Author Report Share Posted July 5, 2023 Put my "new Jeep" to work. My original calculations said that if I sloped the deck 7 degrees starting 60 inches forward off the ET kingpin latching circle, the Jeep differential should clear by about two inches. Hmm, a few AttaBoys should becoming my way. Next task to design the ramps and see what happens with 8 footers instead of 10 footers (my original plan). Ain't engineering a blast!!

Wrknrvr Posted July 5, 2023 Report Share Posted July 5, 2023 I load my Jeep two with 7’6” ramps. Where they hook together in the middle, I can raise they jack stands up say 2” . That helps with the clearance situation i will measure my total length of the ramps tomorrow. I think they are just over 14’ when put together. I am going to load my Jeep tomorrow. So I can measure and get pictures also. Also dumping the air gives some clearance with the hitch head.. Quote Link to comment Share on other sites More sharing options...
rickeieio Posted July 5, 2023 Report Share Posted July 5, 2023 Henry, when you do your calculations of under vehicle clearances, don't forget suspension sag for when Round Boy is in the driver's seat.

phoenix2013 Posted July 6, 2023 Author Report Share Posted July 6, 2023 Jeep working up an eight foot ramp Could be close over the ET ET can be easily modified to temporarily dump its air bags which lowers the head by 3 inches. Once the Jeep climbs up the incline it will easily clear the front of the ET. Quote Link to comment Share on other sites More sharing options...
Parrformance Posted July 6, 2023 Report Share Posted July 6, 2023 I use a set of 10 foot ramps up to a deck with no dove tail. The Jeep handles the incline the best in 4 wheel low range. I cannot speak to the clearance issue as I am unable to use a weight bearing hitch on my truck due to Government overreach in Florida.

Wrknrvr Posted July 6, 2023 Report Share Posted July 6, 2023 I was thinking that you could maybe use a good set of short car ramps to gain a 6” or more in elevation, at the beginning of the ramps. That way you could still store the ramps underneath the bed. Quote Link to comment Share on other sites More sharing options...

phoenix2013 Posted July 15, 2023 Author Report Share Posted July 15, 2023 Since I am sharing this design process, I want to point out few "philosophical" aspects of engineering where ideal meets reality. Rule # 1, "listen to the fabricator". Like the welder working on this truck. He's got decades of experience and can spot fupas, like, "you know this bed ain't coming off the truck unless we slide it back about an inch before we start lifting it". The bed will have to come off to finish welding, painting, mount accessories, etc. The deck assembly had to be modified slightly to allow for rear movement clearance. I also wanted to make sure we didn't trap the ET inside the bed, pretty common on many bed designs which I cursed when I had to remove ETs to work on them, or upgrade them. What you see in the above picture is the solution to both issues. The ET gets an oversize rear plate which when removed exposes the ET mounting rails for sliding it out. It also exposes the bed stiffeners for unbolting and for watching the bed clearance while lifting. Rule # 2, "give the fabricator everything he needs to proceed and not scratch his head". Below is what he got to start. Not only did he get the assembly drawing but also individual drawings how to fabricate the pieces, like the -05s cut left and right with their compound angles. Rule #3, "design ideal but stay flexible". I haven't seen truck yet that did not have "surprises". This one in particular has "issues" both in horizontal and vertical plane, hence the note on page 2 of the assembly drawing. I don't care if the bed is off kilter, you'll never see it on something this big, but I have to have my 12 inches to properly mount the slide drawer. The next challenge will be the side skins extending from the rear to the tires. These will be curved in front to give the tire well that "fender" look and will incorporate the door to cover the slide tray. I already told the fabricator, "don't you dare to cut that expensive 3/16 steel plate to my drawings until you do this. Make them out of cardboard before you torch the steel. Isn't this fun.

rickeieio Posted July 15, 2023 Report Share Posted July 15, 2023 When we built our bed, in my long winded thread titled "Bed Build Planning", I admitted to "stealing" ideas from others' bed builds. Making cardboard templates was one of them. My shop princess got pretty good at making the templates so I could plasma torch the side panels. Thank heavens I was paying attention to you when you built the yellow (Bandbuds) truck. Keep the ideas coming. I may need them if I ever build another bed.

phoenix2013 Posted July 15, 2023 Author Report Share Posted July 15, 2023 Bandbuds truck was the culmination of my truck converting career (until now). Finishing it in the subzero February weather caused serious reflection and a need to solve a problem, actually half a problem. Wife was vacationing in the rig in Florida while I was "converting" in February New Hampshire. Upon driving to Florida I was contemplating a solution to "present" to wife. She liked the idea. By April we delivered on the idea. Incidentally, the truck welcomed me when I arrived. Said to me, "Glad you made it down, incidentally I wasn't going back to friggin' cold New Hampshire no matter what". Quote Link to comment Share on other sites More sharing options...
