I can come up with a solution or two for you, but the cable on the Curt # C55774 that you looked at measures about a foot long, so unless you have some slack in the motorhome's tow package harness that would make up that extra foot for you, you would need to make some modifications to an existing product.

The first alternative would be to use the # HM40975-11998, and cut off the US car connector on the motorhome and hardwire the pigtail from this connector into the tow package wiring. Be sure to look at the wire color code chart on the linked product page, because there's more than one accepted wiring color convention. I'd recommend using heat shrink tubing like # DW05450..

The second option would not require you to cut the plug off the tow package wire harness on your motorhome, but you would need to purchase a harness and make a modification to it. Use the # 20140, and cut one of the plugs off, leaving enough wire with the plug so that it can be connected to the bare wires on the other side of the harness, color for color using heat-shrink butt connectors like # DW05745-5. For a connector, use the # HM40975. Both options would provide more wire than you actually need, but you can bundle everything up under the motorhome and secure it with zip ties.
