TRX Fiend
How wide is the trx outside of tire to outside of tire? The advantage has an adjustable width, but the second set of holes is narrower. I don't think it would be a big deal to add a set on the other side and move it out a bit further. The other option I would consider is getting plates made that would go under the tires that extend out 6" or so on the outside with gussets underneath just to provide support under the whole tire. I'd rather do that than buy a gigantic lift that's really not needed.
