Id say you are correct, its definitely not the ideal TT & TV for me to travel far and often. It will do it but it will be very hard on the equipment.
The main purpose is to get the TT to local campsites and it will do it safely in my opinion. The 150 mile trip was an optional thing that we thought about doing but Id rather not do it now that I know how hard it is on the truck. If long trips were something we were into I would get a truck more suited for the job.
