Very odd question about lowboy trailer I'm sure.

Hello all, thank you for your experience in everything you do to keep this economy going. To start things off, I don't drive rigs yet, but I aspire to someday. I have driven 38' box comfortably. I'm just going to jump right in and ask. I'm sure most of you have heard of tiny houses, I would like to build on a lowboy style frame with a deck over. My material weight not including trailer is around 13k lbs, as far as home design. This will be permanently attached, as a home. The trailer will be custom made to fit, 48'-53' with 11'8" on deckover part included. So let's say 12' deckover with 36'-41' lowboy style beyond that. Lowboy ground clearance ideally about 1'-13". Gn will be from 4'-53" ( not sure how that works yet), would like to have it setup to pull from a 1985 d350 dodge with a flatbed. My questions are how I should design frame to weigh less and still be sound, should I just go with a double axle on rear since the weight will be so light, or stick with a triple like I planned, would like outriggers like with cranes since I designed fold outs but I can't find them for lighter applications. If you could point me in the right direction I would be surely appreciative. Thank-you for your time and keep on trucking.

 

The section between the wheels and deckover will be around 24' with the 1'-13" ground clearance.

 

This is close to what I'm thinking but with more ground clearance. I don't necessarily need 1' but I don't want to scrape on land when going over a hill.

 

Just noticed this, lol, I wanting it to be at 8' 6" wide as that's max width without extra permit. I am aware of the 13'6" heght limit, but I'm wondering on a shorter setup on that too. My plans for the house include a system to raise roof height, so I would like to know the real safe height traveling under an overpass as in know road and highway clearance fluctuate depending on road repair.

 

Waiting on flatbed and MRAP axles. 6.7 Cummins diesel is the power. My 1985 d350 is in pieces at the moment, this is a similar picture of what it was before I started.
I'm a Mopar man, but I've started to grow a hard-on for the international crew cab pickups. It's just the international I'm looking at is 56k and 19k beyond budget with trade in and not including the trailer build.
