I've been very happy with the
TravelRite Travel Rack. Have had others and have helped buddies with theirs, this has been the best. It's light in weight, approx.35# (for some reason the advertised weight is 75#), it has only one shin buster, most have two and it has a simple anti rattle system that works.
I use a simple ramp, a 4' plank with a bent metal tab on the end to keep it in place. No problem loading a 200# 100cc trail bike.
A simple modification that will work with any ramp is to add a 2" dolly wheel to one end of the ramp and you can roll it like a wheelbarrow to your MH (I have a long driveway).
