For $60 you can get an adjustable ball mount and not be worried about the minutia, that way you will always be able to compensate. Look here MaxxTow Adjustable-Height Ball Mount - 2" Hitch - 10" Drop, 8" Rise - 5,000 lbs MaxxTow Ball Mounts MT70067

I think the adjustable height models would be great for cases where you may have to tow multiple trailers with the same tug, and have the option of adjusting the hitch for each trailer. However, it is quite heavy compared to a non-adjustable version and in some instances could really lower the clearance between the bottom of your hitch and the ground. I personally would confirm the trailer and hitch heights, and then purchase a unit that is matched to your trailer/tug combination. (It is a whole different issue if you want a WDH).

I found the info on ball and drop etc in the scamp web site and copied it off to take to my hitch people. Sad to say they misread it as 20" or above (Ziebart). It was a good teaching experience for me especially as I survived the 8 1/2 hour drive home with blowout and rush hours and all interstate highways. The 13' scamp unstructions say 16".

Thanks Dave. I checked out the site and was wondering that. I am only going to tow it with my Jeep, so I think it is more than I need and it looked heavy, not to mention more money. So, is my measurement(19 1/4") to the center of the receiver the appropriate way to measure? I'll ask Scamp what 13ft trailer height is. Was I correct on my other observations? Slight drop? So, if I was to get a 2" drop, my center would be 17 1/4" from the ground. Would an ideal trailer height be like a 16" height from the ground?

16" did not work on my 16' scamp. 17 1/2" works.

Sorry to hear that Judi...so glad you are ok. So, the manual says what exactly is 16"? The trailer hitch height to the ground? If so, see my comments, I may be exactly in good shape with the 2" drop.

RE: Post #41. I prefer the solid feel of at least one point anchored to the ground. Plus, adding two more pieces of hardware to deal with in the dark doesn't have that much appeal for moi.

RE: Post RE #42 Also the age of the axle/amount of sag may also figure into ideal hitch ball height.

Bob...it's a new Scamp (re: post #42)

Check out my last post with my specifics, relative to Judi's numbers. Am I thinking correctly?

Exactly right, and why hitch height numbers from other SCAMP owners may not be correct. Best bet is to start with the factory suggested value, and we know that they never make mistreaks

Right, but $60 buys three fixed mounts of different heights, and...

I agree with Deryk. In addition, adjustable mounts usually push the ball further back (bad for adverse load transfer and stability), and they introduce another joint to potentially move and rattle.

I think an adjustable mount would be good to have for those occasional one-time needs, and to confirm the setup for a new trailer, but I wouldn't routinely tow with one.

I don't have an adjustable ball mount... just four fixed mounts of different heights and lengths.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

The standard is to refer to the top of the opening (rather than the centre); assuming this is a 2" receiver that makes it 20-1/4" from ground to the top of the receiver.

Now working from the trailer end...
Assume Scamp's 18" value is correct - that's from ground to the top of the ball but a typical ball is about 3" tall, so the base of the ball would be 15" off the ground.

Putting the two together: the top of the mounting platform for the ball (the ball mount) must be 5-1/4" below the top of the receiver box (20-1/4" minus 15"), so that's about a 5" drop. Ball mounts typically only come in 2" increments of drop, and the receiver will drop a bit under the weight of the trailer anyway, so a ball mount with a 4" drop should be about right. If the correct trailer coupler height is 16" instead of 18", that's a 6" drop... and so on.

H, I assume that you got 2" because you were starting from the middle of the receiver box (instead of the top), and you didn't account for the ball height.

If you hook the new trailer up and find that you want the next ball mount drop higher or lower, just buy one then... they're cheap. You do need a wrench or two to move the ball over from the old mount to the new one, but surely Scamp would have those. The Boy Scouts among us would presumably go to pick up the trailer with three mounts (expected, one higher, one lower) and wrenches...
