Our 18ft travel trailer is a hybrid with 3 drop out double beds, each with it's own privacy curtains, fan and heated mattress. Full kitchen with fridge, microwave and oven, bathroom with shower, Air Conditioning, furnace and an outdoor bar-b-que under a full length awning make this a vacationer's paradise no matter what the weather.
It's a very easy pull for any half ton truck, but it is probably a bit too much for mid-sized SUV's or 1/4 ton trucks. You should have a hitch with a 2" ball, and should use torsion bars. If you don't have that, you can borrow ours.
Here are the specs for the trailer. The GVWR weight of the trailer is 4617 lbs and the hitch weight is 380 lbs
