I’ve been watching the forum for several weeks and just have to build a TD. My basic requirements are similar to Larry and Diane's Outback requirements. I have access to a free 4” diameter aluminum boat trailer my fathers friend built in the mid 60’s. The thing is incredible light and rigid. It has leaf springs which may need to be lightened a bit. It will also need to be shortened a few feet. I think some of the benefits would be.
1) Light weight and rigid
2) Great ground clearance
3) Able to get hubs that match the Toyota Tacoma wheels (would like matching wheels)
4) Best of all the ability to use the TD frame for water storage, after adding a coating to prevent contamination or corrosion and possibly adding baffles to prevent “sloshing”.
Other than welding the aluminum I haven’t discovered any negatives. Then again I’m proud of my thought but not to proud to ask others to poke holes in it. Think this will work given the off road requirements?
