We had an 18 ft Funfinder that we towed with a Ford Escape -no problems unless the weather was very hot and we were going over a steep mountain pass. In that case, we sometimes had to stop half way to give the truck a chance to cool down. Great little trailer though!
We have a Ford F150 now, and it towed the Funfinder very easily.
We did recently sell it and got Viewfinder V19FK.... only a foot longer, but with the v front you gain a lot more space. Love the layout. Same mileage as the smaller trailer, in part because of the v front.
Good luck and have fun whatever you decide!
