Looking at the photo on the right, you can see that there is a minimum distance required to allow the ramp to be emplaced and the scooter lined up for loading (or unloading.) This amounts to another full width parking space.

It happens that campsites rarely have the needed space available here when the RV is situated in its "site."

In addition to required horizontal space, the end of the ramp must be vertically no lower than the bottom of the RV's rear tires - and in fact, a little higher is desirable. This is because the scooter has very little ground clearance below its center-stand, and this stand may hit the "break-over" point (where the ramp attaches to the horizontal carrying channel.)

If this happens, a logistical horror story develops: You are alongside the scooter, pushing it up the fairly steep incline, your arms at, or above, shoulder level, and the scooter will not go forward or backward. You cannot let go in order to move to the back of the scooter and lift it. You have no leverage to push it over the obstruction.

If no help is nearby, you might have to let the scooter fall sideways, then drag it off the ramp and pick it up from the ground before it leaks much fuel and oil. This is nearly certain to damage trim and controls; costly, and hard to find replacements.

The answer to this problem is to get some help: 2 people are sometimes needed to load or unload the scooter. Not always, but when needed, help is absolutely essential!

In our case, my wife is the usual assistant, and since she is a "small person" and since we are both getting too old to look forward to broken bones, we have installed this winch to "help the helper."

I bought this "boat trailer winch" at WalMart for less than $30, added a short section of "C" channel and a few 3/8" bolts, nuts and washers for another $10 or so.

While I balance and guide the scooter, Annabelle can easily pull it up the ramp - even over the hangup point if required - using the substantial leverage afforded by the winch.
