Carrying my motorcycle

I had posted just a moment ago thinking you wanted to hang the cycle off the back of the TT. But I see that you want to use a lift on the rear of the pickup and a hitch extension. I think that is possible if done carefully given that many TC folks use hitch extensions and tow large boats or trailers. However, you mention that your truck is a 1/2 ton so you'll likely be far over acceptable load ratings.

look at motorcycle loaders for your truck .Just push a button and winch loads the bike. Riding up ramps is risky

Or just trade your trailer for a toy hauler of the same length. Problem solved.

I doubt your frame could handle the weight and your bike hanging off the back of the trailer would be beat to death over bumps and such, assuming nothing else broke. Sounds to me like a recipe for disaster but go ahead and try it and let know how it goes.

You may not like ramps for the truck, but that may be the only way to do it safely.

Putting that much weight, I mean you're looking at probably around 750+ lbs. hanging off the end of the truck, plus the hitch weight. Probably won't need power steering with that setup. :) I think it would make for some real white-knuckle driving.

Ramps in the truck bed.

You will probably be over your TV payload.
