5th wheel vs travel trailer
Your vehicle should pull either trailer easily. The most important consideration is the LOADED WEIGHT.
However, I pull a 5800# trailer with my 2003 GMC Savana Van with all wheel drive. This is only a half ton vehicle so I am limited to 6250#'s. I have the van because I must use a handicap scooter to get around. If not, I would have a pickup and tow a 5th wheel trailer.
WHY? MOST OF THEM COME WITH GENERATORS OR CAN ADD A GENERATOR EASILY!!!. There is nothing worse than having a trailer and not being able to stop in a rest area or along a beautiful roadside vista because you can't plug in to power your A/C!!!
So, I say; "Go for the 5th Wheel"!
