I can see several problematic situations develop here. When you encounter a low spot in the road or trail the hitch could potentially hit the bottom of the camper because the pivot point is all the way forward under the camper. I like the hitch extension because it keeps the trailer/truck pivot point behind the camper not under the camper as with the trailer tongue extension.
I would prefer the hitch extension but I do not believe Reese make a heavy duty version. I made my own extension out of solid steel bar and added stabilizer bars on each side to prevent the extension hitch from moving left and right.
