I also prefer the extended tongue method. The above pic is my current setup. The Arctic Fox 1150 is a very roomy camper with a long rear overhang, but does not hang down low so it provides good clearance for the tongue. I had this trailer built with an extended tongue, and I had it mounted low. In combination with a dropped hitch, there is no clearance issue. I am careful to avoid entrances with dramatic slope changes that could cause a problem.
This is my second enclosed trailer like this, the first one I had extended by a welding shop.
The first camper I used was a Lance, and it hung down lower, so I had a bunch of 2 x 6's under it to raise it 1.5".
I also ran it with a Real-Lite 10.5' camper, and that was in between the AF and the Lance as far as clearance.
One observation I have made in the last 100,000 miles of driving this truck with the camper on it, is that the fuel mileage is exactly the same whether I am towing the enclosed trailer, an open trailer, or nothing at all.
I would recommend that you consider an enclosed trailer. It keeps your stuff more clean and safe.
Another thing, when you get into these heavier trailers, you don't need the old rule of 10% tongue weight. 5% is plenty, and is less stressful on your equipment, and rides and handles better.
