I would also go with D-rings, you could take them with you with bolts and install them after camper is loaded. Can you back your truck under the camper or will you have to put it on with a forklift? You may need wide swing out brackets.

I am not sure I understand the question about backing under vs forklift - I don't have a forklift nor was I planning on buying one - my understanding was that I would be backing under it after I buy it (?). Thanks!
