I take it you have no problem pulling it with your "little V6". Next question is do you have 6-1/2 foot bed? Does it need a sliding hitch?
I'd highly recommend it. I was in the "not necessary" camp when I had my Cougar. When I got my Jayco almost clipped my cab, thankfully I caught it just in time. Now I'm in the better safe than sorry group. I have a 6 3/4 foot bed.
