What are my options besides a Super Hitch?

An option is to keep the camper length to that of your bed and avoid the extension. I was specific about this as some of my favorite spots involve fording small streams and a camper that hangs over the back can bottom out. Came to this realization by watching and helping a guy who was sooo stuck.

I used a Reese Towbeast when I was in your situation. You want to really watch the weight of the camper, an F250 is not known for having a lot of payload available. My F250 is around 2600 lbs of payload. I used a 24" extension and used a dual-cam WD hitch with 1200 lb bars for an 8,000 lb trailer. It really picked the back of the truck up, counter-acting the leverage, and when loaded the truck was perfectly level. My truck (Dodge 2500 at the time) was about exactly at it's GVWR when loaded for the road with the camper and the trailer, so it can be done.

The weight limit is more than just for the extension. The leverage will really increase the load on the hitch to frame bolts, and the extension puts far more weight on the rear axle than without.

I made a extension for my BIL's 96 chevy. He pulled a 19' I/O. Stacked some tubing that they used to transport semi tractors. Had two slide in trays that he would carry things on under the overhang.

You just have to beef it up so the length will support the weight. Bumps in the road can easily double the load on the hitch.

Leverage is leverage, not a lot you can do about using an extension.

A WDH on the trailer is a good idea as well.

Resse 2.5" or Superhitch, that's about it...

does the 250 have the 2.5" receiver like the 350? If so reese makes a 2.5" extension
