To all you people who think the sky will fall if you have your camper COG slightly behind the rear axle - what do you think happens when you hitch a heavy trailer at the rear bumper, four feet behind the rear axle?
And how about the guys who add four more feet with a hitch extension?
Not to beat this subject to death . . .
You are comparing apples to oranges. Put a 4,000 lb. camper on the back of a truck and the truck's rear suspension has to carry all 4,000 lbs. Hitch a 4,000 lb. trailer up and you're only adding 400 lbs. of tongue weight.
If you're pulling a really heavy trailer, you're required to use a Weight Distributing Hitch, which makes the front end carry a lot of the load.
And as for hitch extensions, IIRC, the hitch manufacturers require you to DERATE the receiver and carry LESS tongue Weight when using a hitch extension.
(The Torklift Super Truss being a special case.)
