2000 3124 questions

Hi, I am considering the 2000 3124 in the for sale section, I have seen pics, but not the unit, we are about 3 hours away. I suspect it's too heavy for our car to tow, even going light and taking out what we can. Our car is a toyota sienna minivan, tow capacity of 3500lbs and tongue capacity of 350lbs. Has anyone towed a 3124 with a minivan?
I noticed in the pics that it needs lots of TLC and the flaps/seems where the top and bottom halves meet are torn and dirty. Can they be replaced?
I also think someone else has posted about buying this unit and I don't want to interfere with their purchase. Thank you, Reni
