Towing a fifth wheel with a 6" lift. Will I have issues?

Well the listed height of the 5er is 143" 11,-11" tall so it could likely be lifted to match the TV, BUT!!!! I have a stock height 2001 Ram, and the floor of our 5er is about 3'+ off the ground, I can't see what this guy will end up with.

To the OP Donn and I don't see eye to eye too often, BUT why do you want to tow a 5er with a TV with a 6" lift, either get a TT, or drop the TV back down to stock height.

Just like Cummins12V98 pointed out, Lifted TV and 5ers are not stable.
