I have 18' CC that weighs about 2200# ready to go. I presently tow it with a Jeep Liberty to the local ramp. The Jeep pulls it without any problems. MY wife and I want to take some road trips with the boat. I feel the Jeep is a little light for over the road trips. The trailer does not have any brakes. It gets dunked in salt water every weekend form April to Oct and I did not want to deal with the maintence. Would a Envoy make a good over the road vehicle and be able to stop my trailer with out adding brakes? Have there been any maintence problems with a newer Envoy?
