Well keep pushing. Your lawyer will be able to advise you of what damages to seek. There's a difference between just getting any old run of the mill car whacked and losing your "house."
Remember you're not taking advantage, you're just trying to get back to where you were before YOU got hit.
I know you're single, but if you can hook up a toad then you can hook up a TT. Get a vehicle large enough to haul a small TT then you're set. Good TTs are cheap compared to all other rvs and dime a dozen everywhere. May be a good way to get more for less to continue rving.
