according to this article, any modification decreases your capacity by 50%.

How to Calculate Trailer Hitch and Towing Capacity When Using A Hitch Adapter or a Hitch Extender

Use an adapter when you have a ball mount shank size (the shank is the part that fits into the receiver tube on the trailer hitch) that is not the same size as the square tube on the trailer hitch (the "receiver" tube). For example, if you have a hitch ball mounted on a 2-inch shank and you want to fit that to a trailer hitch that has a 1.25-inch receiver tube, you would need a 2-inch to 1.25-inch hitch adapter.
Use a hitch extender when you need to increase the space between your tow vehicle and the trailer you are towing.

Since using an adapter (or a hitch extender) lowers the maximum capacity of your trailer hitch, you need to be aware of the new maximum trailer weight and tongue weight your trailer hitch can safely carry. Use the following information to calculate your new towing capacity when using a hitch adapter or extender.

Your new maximum gross trailer weight (GTW) is the LOWEST of the following:

50% of the Gross Trailer Weight (GTW) rating of the trailer hitch (if the trailer hitch GTW rating is 3000 lbs, this number would be 1500 - half of 3000 lbs.).
The vehicle's towing capacity as stated in the vehicles owner's manual (let's use 2000 lbs as an example here).
the adapter's maximum trailer weight rating (usually 3500 lbs.)
So in the above example, the LOWEST weight is 1500 lbs., so do NOT attempt to tow anything weighing over 1500 lbs.
Your new maximum tongue weight (TW) is the LOWEST of the following:

50% of the tongue weight (TW) rating of the trailer hitch (if the trailer hitch TW rating is 400 lbs, this number would be 200 - half of 400 lbs.).
the adapter's maximum tongue weight rating (usually 300 lbs.)
So in the above example, the LOWEST tongue weight is 200 lbs., so do NOT attempt to tow any trailer that puts MORE THAN 200 lbs. of weight on the tongue.
In this combination of tow vehicle, trailer hitch, and hitch adapter you can tow any trailer that weighs 1500 lbs. or less AND places 200 lbs. or less weight on the tongue. Anything heavier than that would be unsafe with this combination of vehicle, trailer hitch, and adapter.
Always follow these safety precautions:

That Hitch Extender will place additional load on your tow vehicle, not less. And a 13' Sacamp can easily have 225-250 lbs of hitch weight. If you derate the hitch by 30% when using one of these, that puts your hitches capacity at 210 lbs, less than your load weight. Any thing that places the ball further from the center of the rear axle sounds like a bad idea to this guy.

LOL Al, I suspect what you experiences may have been a towing experiences that once you have done it you know what not to do in order to avoid ever repeating.

Yup.BTDT,and hope not to repeat.Plus,I now have twin group 27's and two 20 pound tanks on the A frame,and even testing in town,around corners,it is just too close.
Plus,that last bad experience is all the fault of my navigator!

There has been a couple of times when I have made tonque extenders that consist of an "A" shaped member that matches the trailer and extends an extra 24" in front of the old coupling (where I've mounted a ball) up to a new coupling that will make the TV connection.
In effect it gives you a longer trailer with the axle mounted farther back. Reduces tonque weight and makes backing up much easier....not to mention tailgate use.

It is a bad idea. Our local well known towing specialist makes every effort to get the ball as close to the back bumper as possible.

If you review the physics involved you will see that by extending the ball back you are increasing the overhang to wheelbase ratio. "In effect" your combination will act as if you have a shorter vehicle wheelbase.

As others have stated it also adds additional stress on the receiver hardware.

Since the tongue jack seems to be the culprit here, why not replace it with a sidewinder and keep the stock set up?

As Patvetzal suggests above, extending the trailer would be a better approach. With dual batteries and dual propane tanks the extension would lessen the tongue weight at the TV and help the trailer balance. Perhaps you could scab onto the side of the existing tongue back under the trailer which would stiffen the stock tongue. Welding access would be tough with the body on, so some creativity would be in order. A weld on solution would be preferable to a bolt on.

we have the same sort of problem with our liberty. had to remove the spare tire to hook up. i bought a longer ball plug so it sticks out far enough. yes i can feel the trailer a little more then when it was tight to the car. but still no problems with the set up.

I towed with a Liberty CRD and I ended up removing the tongue jack vs spare tire and installed a swing up jack. Worked for me.

After reading these posts, you all have most likely solved a problem for me....last fall I was going to use my tractor to back the scamp, but i was afraid the tongue would hit those big back tires on the tractor unless i really watched it. Then i was going to use the garden tractor and thought the same thing......finally used the tow vehicle which is a 98 dodge ram, with a shell and sometimes hard to see thru. I was trying to move from the scamp's usual spot to another spot that had a tree in back, the garage on one side, another shed, and a 4 bay shed in front. Room to manuver with caution.

One of these days i will make it down to the local auto store and get an extender as i can most likely use it for other things. thanks
