I have a 2004 Toyota 4Runner with the V6 and we just bought a 2012 Jayco X18D. The $runner has no problem pulling the camper up to about 70 mph... then you really have to put a lot of peddel to the floor to maintain speed.
I do recomend a weight distribution hitch, I wouldn't want to go verry far without one... the truck squats in the rear and the steering feels a little light without it .. long and short of it is that the 18 ft pulls just fine with the 4Runner.

PS TTChamp is for a game we play.... had no idea it had a completely different meaning on this forum. :confused:
