aluminium frame, utopia?

I talked with my dad than we will probably need to re build the frame on our futur AS.

So my dad came with the idea to re build the new frame in aluminium like those industries did with those pick up (like the new F150 ford I think).

So the question : Is it possible to build a new AS frame in aluminium.

I know it will not be the same cost.

Can be done, and has been done. I remember someone had a boat trailer shop custom build one out of aluminum. Requires more aluminum to make up for the lower strength. Also, aluminum is more susceptible to fatigue failure than steel. Welding the aluminum is also more labor intensive. Aluminum is also more expensive.
You'd probably be better off with a well designed and slightly reinforced/strengthened steel frame that is powder coated or just well coated. You could make one a little taller to fit some bigger tanks and a stiffer back end to be able to put on a bike rack if desired.

Hi, Ford built the body of the new F-150 out of aluminum, not the frame. Aluminum frames have been discussed on this forum, but they could have problems as mentioned in the above post. Also the coupler, axles and other items would still be made out of steel and have to be bolted in place instead of welded. One forum member made a complete frame for his Argosy out of stainless steel.

IMHO, while a good aluminum frame can be built, I don't see the extra cost and trouble being worth it.

Steel is SO easy to work with, aluminum will require a lot more work, and a lot more engineering.

Our last SOB trailer had a galvanised steel frame which held up extremely well - even to being washed with winter road salt.

Unfortunately the rest of the trailer didn't hold up as well! We eventually got rid of it due to high cost of repairing damage to the flooring and laminated sidewalls due to recurring water leaks - but the frame looked just like new!

I wish our AS had been designed with a composite floor, a galvanised frame - and no enclosed belly pan!
