If you have some spare change laying around, maybe one of these Tow Rigs would fit the bill. http://californiatruckinconcepts.com
Someday I am going to build one of these but like a toy hauler where the back folds down and I can pull my trail junk inside imp:
I have actually been inside one of these rigs, last weekenk at the dunes, the inside is unbelievable, and it spells comfort in every way!!! The guy actually had a trailer for his toys, that was just as nice. Must be nice to have lot's of $$$$..waytogo
