I disagree. When any style of hitch is hooked up, they are semi permanently attached to the TT.... But none of that weight should be used to calculate TW.... TW percentage is a figure used to determine the INHERENT stability of the TT alone....If you cheat on this figure, you only cheat yourself.

And I disagree with you. [emoticon]
Do you not add the weight of a standard hitch to the payload of a truck before it is hooked up to the trailer? The same exact thing applies to the HA/PP hitches. They are left on the trailer all the time just like the batteries or propane bottles and IMO should be counted as part of the tongue weight. If you weigh the tongue, you put down the front jack on a scale and the result you get would be a weight that includes the HA/PP hitch. It is not removed and inserted into the truck like a standard hitch - only the stinger is , which becomes just like the hitch head and shank of a normal hitch and would not be include in the tongue weight. The hitch becomes, in essence, another coupler- just a very fancy, expensive one which is attached to the trailer tongue and should be counted in the tongue weight. [emoticon]

So you disagree..... Why do you think he is not happy with the way it tows?
My money is on the Propride's weight being included in the TW, making the TT inherently unstable.... But the design of the Propride makes sway impossible even with low TW.... That doesn't mean it will feel right. It is just masking the underlying issue.

The main body of the HA is left bolted to the tongue when done towing. Same as the propane tanks, batteries or the chain pull ups.

Unlike a standard WDH where the main body is slipped into the receiver the HA is attached to the tongue.

One COULD leave a traditional WD hitch attached to the TT.. Simply release the pressure on the bars, pull the hitch pin on the drawbar, and drive away. Not any different than the Propride/HA.

Just as a follow up to the friendly folks here, I pulled the trigger on the Grand Design 2670MK at the Tampa RV show. Taking delivery early March. Going up to MI to visit Pro Pride (we have friends in the area to visit). Still perusing these (and other)forums, but leaning toward the PP, but it's a pricey addition.
