Lengthen the tongue of the trailer the same length of the overhang of the slide in camper..... DO NOT EXTEND THE TRUCK HITCH!!  It's a Physics thing.

I will beg to differ.  If you use the torklift superhitch, you are getting a tested, proven, load rated solution to your problem.  When you extend the tongue of your trailer, you aren't quite sure of what you're getting.  Hopefully the person who does the job does it right.  Now, all that having been said, I had a tongue extension put on my trailer. They beefed up the trailer frame, then they added the extension. It was a separate piece that had a ball that went into the coupler, bolted to the frame, and was built like a brick poop house.  However.....I was always worried because I didn't know what that hitch was rated for since it was basically someone's home project. It worked fine for a steel 4 horse stock trailer.  My camper overhang was a GOOD 3 feet.  Big.  If I had the money I'd do the torklift superhitch.  I had a lot more bounce of the trailer when the tongue extension was in place.   With torklift The research and numbers are all there.  If I had a new truck and trailer worth THOUSANDS of dollars I would not cut corners on the hitch situation.  Do some asking on truck camper forums, and the satisfaction with the torklift superhitch is overwhealming.  I believe they even have a picture or video of a truck pulling a horse trailer with a truck camper on their website.  You will need to use a weight distribution system though....if I remember correctly.   This is just my honest opinion from experience.  I've never been one to question physics, but someone from torklift must have.  There are LOTS of people using these hitch systems without problem.

That looks like the tail wagging the dog..... No thanks, I'll pass on that "quick fix".

Thanks Amanda....

I haven't made a decision yet, but I have spoken to two people who are using the Superhitch successfully. But....there are limitations....road dips, reduced speed in the wind, and plain old careful driving (don't weave!...leave the beer at home!). So, I'm continuing my research, but my options are limited. The trailer is new so I won't be welding anything untested onto it, and the camper is new so I won't be selling it.

Thanks again,

I carried campers and pulled BP trailers for many years. Even with the camper specials and trailer towing package options, a stock SRW truck does some bobbing and weaving under certain conditions. You will be down on your helpers with the combination, and with any corner or wind, the truck will sway. Air bags or Timbrens are a must for stability. You can do a search for the comparisons.

Extending the hitch makes matters worse, it adds additional weight behind the axle in greater amounts than the actual tongue weight. It's risky finding a competent welder to cut up a good trailer, but adding the extra length to the tongue is a safer way to go. You will only increase the turning radius of the trailer and add a small amount to the tongue weight. If the conversion is done correctly, it won't effect your trailer's stability or towing capabilities.

With the combination, you will be up against most 3/4 and 1 ton trucks' weight carrying capabilities. Be careful in cross winds and jack knifing when backing up.
