You install a key on the camper. It causes the hitch plate to turn when the camper turns. There are two tracks in the hitch and it just turns. I was amazed at how simple the whole thing was. I can go clear to 90 degrees without hitting the truck. It was pricey, but I would only have to hit the truck with the trailer once to cause a huge problem.

 

I dont care how much of an offset the hitch has. The weight will be placed where ever it comes down off the camper not 5 inches forward of the axle where it mounts. It would have to be ridgidly mounted to the camper then atach to the truck 5 inches forward of the axle to put the weight 5 inches forward but it is not ridgidly mounted to the camper so the weight will be placed directly under where ever the pin of the camper is.

As far as puting a golf cart in teh box then pulling a TT that is no problem. This is how I did it before I bought my toy hauler. I pulled it 1800 miles round trip like this with no isues what so ever. I dident have a WD hitch or air bags. This is 100% stock suspension. Camper was just sitting on a ball on standerd receiver. With this load the truck just sat level. We even left the ATVs on the truck all week driving around Colorado and up Pikes Peak with no isues.

 

I pull a 11200 lb 5er with two slides.
My pin is zero over my 2500 short bed Dodge trucks rear axles. That way I get the full 10" of sliding ability away from the trucks cab from my 16K Reese manual sliding hitch. I seldom use the manual slider. One big advantage of a manual slider I found is it puts the pin 10" behind the trucks rear axle at all times. Steering input is much quicker while backing in tight situations, than the pin in front of or over the rear axle.
