Our travel trailer has a max weight of 7600#. So it seems only the 3 big trucks in the 2500/250 series will cut it. Or maybe something else? My question is, if we are wanting to only spend around $20...
With a max weight of 7600 and the kids, you might want to look at a Chevy Express 3500 van. I see 2012s with under 20000 miles on the odometer for around $22000 all the time. 10000 lb towing capacity and plenty of room for kids.
