I'm hoping to haul a 32ft semi trailer i found with a big lift gate on it. Pull my car up onto the lift and raise it to trailer height and drive in just like it should be. This is going to give me so much more room in the RV and the shop. Should be able to get all me gear plus two cars. I'm not traveling more than say 100 to 250 miles at time and lock the beast in at 50mph and I'll be just fine. This combo will let me boon-dock a lot more over a low to the ground enclosed car trailer. Plus the extra brakes will be super nice out there in that trailer, with not very much weight on them. I'm new to semi stuff so i assume I'll be able to just tie in brake lines for the trailer. I'm not even sure at this point how the trailer brakes are activated when stopping a semi? always a learning curve. Need to find a roof wind cowling off a semi truck to mount on the bus to get that air over the higher trailer. I think that thread said they were using a cummin's 5.9 engine with a 545. I'm planning on a dt466 and it has 643 Allison in it. I read some where the 545 Allison was rated to 30k lbs and the 643 was rated to 72k lbs. Were building some big frame mounted oil coolers for the engine and transmission to keep it cool and get them out of the radiator. If it does what I need and I need more space a bigger trailer will always be an option. This will surely turn better than any bumper trailer. Hoping down the road on this project that using a trailer will give me a ton of space for solar panels when I'm down south. There is just some thing so cool to think you can take the sun and make ice with it and run the blender.
My thoughts on the decking were along the same lines.
I figured that I would cover the deck area with something like Choice Dek or Trex from Lowes instead of 2x6's. It would be lighter weight, never need painting or sealing and since there won't ever be anything heavy on it I believe it would do fine.
I may or may not leave the sheet metal in place. If I did I would probably clean it, prime it and paint it with a rubberized paint before laying the deck over it.
OTOH if I remove it, then water can just run off the deck boards and down.
Either way I think everything below it would get a couple of coats of undercoat to try and stay ahead of the rust.
When I talk to folks about this idea, I usually refer to it as being either "insane" or "insanely brilliant" and say that the jury is still out on that one.
