Big5er Posted April 8, 2019 Report Share Posted April 8, 2019 I saw the post where someone built a storage box on the end of the bed, under the trailer. I think I even commented on the thread but i can't find it now. I want more pictures! Who posted it?? My truck is heading back to Herrin soon to get my generator box built and the genset mounted. I think I have it all engineered in my head but a few more ideas never hurt.

Big5er Posted April 9, 2019 Author Report Share Posted April 9, 2019 Chet, that's it! I'm going to mount generator back there in a box. It's too big to mount behind the fairings so its gonna go back there. I would have preferred one smaller but I latched on to a commercial grade 7.5kw Onan QD for a price that was too good to pass up. Do you know how many hours I can run a genset on 275 gallons of diesel? I'll send Brad a message and ask for more pics of his build. Thanks again. Quickthrotl, thanks but I'm wanting to mount one to the rear of the truck, between it and the trailer.

Steve from SoCal Posted April 14, 2019 Report Share Posted April 14, 2019 Roger, How low are the boxes aired up ? Phil, My rear body is actually saddle bags on the frame. Your truck has a body, are you going to cantilever off the frame? The hitch on my truck is not far back 8~10" behind the axle, trailer clearance is close. That is with a 90" wide straight body, a gen box alone would be about 48~56" wide?

I'm basically going to add a pair of receiver hitches and mount a stinger on the rear of the truck using them at the bottom and pins at the top to control bounce. My hitch is much further to the rear than yours so I'm going to use that wasted space under the front of the 5er.

NeverEasy Posted April 15, 2019 Report Share Posted April 15, 2019 I am interested in your install. I bought an Onan 6.5 diesel and want to mount it back there. It is 30 long x 25 tall x 24 wide. Are you going to shock mount it in any way or will it be a rigid mount to the receivers? I noted you will use two receivers. I was thinking the one installed for tow-behind trailers and outside support arms sitting on the cross member. I have the base plate ready and contemplating the front and back needs for air-flow while running/weather while in transit. It probably will not happen until after the ECR.

Big5er Posted April 15, 2019 Author Report Share Posted April 15, 2019 Chet, the 7.5 is vented, cooled and exhausted from the bottom and designed to be installed in a compartment so I dont need to worry about airflow. I had planned on a rigid mount but if Herrin has any suggestions, I am open to them. I have one receiver hitch already but thought two would have less play and allow for more stability. Again, If Larry has a better idea I'm open to suggestions.

Darryl&Rita Posted April 15, 2019 Report Share Posted April 15, 2019 With the weight of a diesel generator, dual mounts are almost a necessity. Especially with the balance point being a moving target. I initially built one for a single point, but it flopped around enough I quickly tired of the noise and motion. It was originally mounted on a LDT, but still. I have been wrong before, I'll probably be wrong again. 2000 Kenworth T 2000 w/N-14 and 10 speed Gen1 Autoshift, deck built by Star Fabrication 2006 smart fourtwo cdi cabriolet 2007 32.5' Fleetwood QuantumPlease e-mail us here.

Big5er Posted April 15, 2019 Author Report Share Posted April 15, 2019 Darryl, that is why I was planning for pins/bolts/some other attachment at the top, to help stop that movement. In your opinion will that help/be enough? Needless to say I will have to move the rear ID lamps and the camera/trailer light connections. The picture shows where I plan to add receiver hitches, the pins and the rough size/position of the box.

Darryl&Rita Posted April 15, 2019 Report Share Posted April 15, 2019 Two points of mounts is enough, by themselves. Only when a single point mount is used, is something needed to tame the flop. People use wedges, clips, and all manner of things to calm the motion, but two mounts are all that's needed. The weight of the load will control fore-aft movement and the two mounts with control the side to side motion. I have been wrong before, I'll probably be wrong again. 2000 Kenworth T 2000 w/N-14 and 10 speed Gen1 Autoshift, deck built by Star Fabrication 2006 smart fourtwo cdi cabriolet 2007 32.5' Fleetwood QuantumPlease e-mail us here.

Big5er Posted April 15, 2019 Author Report Share Posted April 15, 2019 I figured the weight would control the slop in the receivers but since these uprights are there, I thought pinning it couldn't hurt. That generator weighs in around 600 lbs, plus the box.

Steve from SoCal Posted April 16, 2019 Report Share Posted April 16, 2019 Phil, If you triangulate the outer tray to the points shown, that will stiffen up the whole thing. I am not a fan of cantilevered loads on the very back of a truck body. It can get pretty bouncy.

HERO Maker Posted April 16, 2019 Report Share Posted April 16, 2019 Phil, while you're at it, have Larry add another step plate across the rear (or side) of the new box. You will like it for getting on top of the bed. Rocky & Sheri Rhoades '01 Volvo 770 2016 DRV Mobile Suites, HoustonHERO Makers Ministry Link to comment Share on other sites More sharing options...

Brad NSW Posted April 17, 2019 Report Share Posted April 17, 2019 Phil, Sent you a message describing my build. Will send pics tomorrow when it's light out so you can see what I was describing. Don't know how much help it will be because I wouldn't be comfortable putting more than 200lbs in it (box weighs just under 100). I did find out things didn't bounce around in there as much as I thought. I'm dual in the rear and have lowered my tire pressure to 80psi per the tire manufacturers load vs pressure chart. Might be helping smooth the ride out. Brad 2010 Freightliner, DD15 Eaton Ultrashift, 2015 New Horizons 5th Wheel.

Jack Mayer Posted April 17, 2019 Report Share Posted April 17, 2019 Phil, I think you are on the right track. You MUST use dual mounts or you will regret it. There would be quite a lot of movement without dual mounting pints. Also, there can be a lot of sag if not supported right, but Larry should be able to handle that. It should work out well assuming you get it stable enough. Just make sure there is a flex line in the fuel line or it will crack on you - but I assume you know that.

Big5er Posted April 17, 2019 Author Report Share Posted April 17, 2019 I am planning on some quick disconnects on the fuel lines and a plug on the 12v from the truck batteries so I CAN remove it if need be. I don't plan to take it off, but who knows? I may use bolts instead of pins for a tighter connection. I'll left Larry figure that out. He's never let me down.

lockmup68 Posted April 18, 2019 Report Share Posted April 18, 2019 Few thoughts: 1. even though it is heavy and unlikely, bolts or locking pins to keep the handsy people at bay 2. Need to relocate the license plate so it is not blocked? or is it acceptable in this case? 3. Are you relocating the light connections? I'm mostly thinking rubbing of trailer wire on the genset. 4. Are you putting the genset in a box? Or just a cradle. Just thinking you don't want someone coming by and starting it up if it is wide open on the back. I do like the location of my genset, but will be a bear once I fix the rear of the bed (raise the bed up to be level and raise the hitch to the correct ride height (current hitch is at 41" vs 48")). Easy to change the genset filters and oil from the ground, but if you need to pull panels off to troubleshoot electrical, too close to airbags (and airbags actually rub a bit when deflated I discovered, I have a small hole in one of the airbags), to get the panel off. I will probably have to raise the genet up to the top of the bed at the sametime. I'm also wondering if the exhaust exiting underneath is going straight to the air filter of the genset and maybe choking it a bit? I'm thinking of putting a 90 on the muffler and routing it further to the outside of the body. Right now just dumps down underneath and right in front of one of the brake cans. 2003 International Eagle 9200i, Cummins ISX, Freedomline 2007 Teton Scottsdale XT4 Link to comment Share on other sites More sharing options...
