Similar Problem for us.
I purchased one of these - with the extended lift due to the height of our Motorhome floor from the ground.
See: http://www.mobile-lifts.com/handy-lift/
or
Handy-LiftIt arrived via UPS. The instructions were clear (but the hole size noted was too small for the bolts - easy to fix, but do not go too large and get a loose fit.)
As with many of my projects, what was to be a four hour job took two partial days. Use care to run the power supply correctly!!
It has provided many enjoyable days for us that otherwise would not have happened.
Oh - and I had to add a 'notch' for tight travel stowage.
Further information - check carefully the planned installation location. I needed to move the external grab bar from the outside to the inside on the other side. (Inside of the open door.) Then after it was all done, I overlooked the fact that the round turntable fitting blocked raising the compartment door - so that compartment only holds items I hope to not need - as I need to lay on the ground to get into it as the door only raises about 12 inches.
