I had an Overbilt Lift on our Monaco Diplomat. It had the three receivers you need. I liked it but loading and unloading in some campgrounds was tough, since it unloaded to the side.
I sold the Overbilt and bought a Rampage that was bolted into the back of my Chevy pickup truck. It was better in the sense, loading and unloading was easier. It was also very scary for my bike which was a 950 pound Harley.
I now use a Cruiser Caddie, which is not scary to load and is less expensive then either the Overbilt or the Rampage. I have it in my Avalanche.
I would tow an Avalanche first, a truck second or if you can't tow a vehicle that can carry your bike, get a Hydralift for the back of the Monaco or second an Overbilt lift..
