Years ago I did the trig...or used a formula provided by one of the companies that makes these lifts. I am talking about hydraulic/reciever lifts.
The weight of my motorcycle (750 pounds) plus the lift (200 pounds), lifted around 3 feet would clear the rear axles max weight by just 300 pounds. However....I would lose 700 pounds from the front. No thanks.
You can buy dollies...where the motorcycle is loaded sideways and the car (toad) goes on the dolly like any other. Or...buy a trailer. Like a lawn service trailer and drill holes for the tie-downs as needed. That works well.
Or....buy a DP. That can, in most cases hold the weight of a reciever-mounted hydraulic motorcycle carrier without problems.
I've only seen ONE gasser with a hydraulic lift...and the headlights were almost looking up at the sky. I have no idea how the rear axle/suspension survived. Steering must have been really scary. (that was in the parking lot of Carlsbad Caverns)
