Take a look at this boana, Gents!

It's a small trailer that connects to the TV that a 5er connects to! It allows an SUV (like the Excursion) to tow a 5th Wheel! It's got it's own breaks, the attachment point is directly over the axle, so it should take most of the hitch weight off the TV.... I know theres GOT to be a draw back to this thing, but it looks AWESOME!
If it is up to snuff, it would enable us to get the camper we ultimately would like to have... which is a 5er.
PLEASE TELL ME SOMEONE HERE HAS EXPERIENCE WITH ONE OF THESE! lol
