If youve got a motor home to hang it off of, youre golden,,& dont be shy to build what ya need to get that bike on & off. Be a pretty crummy vacation to have that thing layin on ya,,

You can mount 2 receivers & use a long ramp. Get the bike on the ramp & lift it into position, then pin it in the second spot. Jacks lift, come-alongs lift, lots of ways to win this safely.

i had the local spring/trailer shop fab me a carrier for thumperclone (165# wet)when they were bending the leaf springs on my 97 2.4l tacoma
it fits into the class 2 reciever and has a reciever for the pop up trailer
hitch
had trouble with the tipping till i bought a collar that straddles the reciever and the ball bar,has a series of 16 set screws and loknuts
no tippies nomore..

I haven't actually tried this, because I haven't needed to. My idea for single-handed loading a bike up a ramp into a pickup, was an electric winch such as the ones used on ATVs. Acquire a suitable winch with a remote control long enough to reach from the winch to the front of the motorcycle, with the motorcycle on the ground at the end of the ramp. The winch can be mounted to the front of the box, or somewhere else with a pulley so the cable runs straight along the ramp. Spool the cable to the bike and attach it thereunto. Holding the remote in one hand (or attaching it with hook-and-loop tape to the bar), use the winch to pull the bike up the ramp. You should only have to balance the bike and walk alongside it. For unloading, park so the bed of the truck slopes slightly downward, then use the winch to control the bike as it rolls out of the truck and down the ramp. The same general idea ought to be workable for a trailer, or even sideways loading such as a bike carrier on the rear of a motorhome.
