I carry one EU2000i on an 24x54 Everthere Aluminum Cargo Carrier, as well as the dual feed fuel tank. That way I stay below the max 100 lbs on the TM rear hitch. If I expect to use the AC I carry the second EU2000i in the TV.
The carrier weighs 29 pounds, and is rated to carry 400 pounds.

If the campsite has hookups, I leave it all at home.
