I've had a motorhome (shudder!) and flat hauling with a tow bar is preferable. As low as a Boxster is, it will be a pain to get up on a trailer. I know you want your Box, but I think I'd get rid of it, too. Get something like a 4x4 Jeep or small pickup. Older ones with real 4wd are best, you can shift the transfer case into neutral. If you're running a diesel, you'll have to deal with soot, too. And road debris.

I used to have a Chevy Tracker, it was perfect for towing and it could be set up as a convertible. But finding nice ones that aren't beat down is kinda tough.
