Questions about Cargo Trailers behind RV

I chose this trailer for a couple of reasons. First single axle vs dual, two extra tires and axle toll. Max Gross Weight for the whole thing is about 3k lbs, which is less than the tow rating on the motorhome. Using the dual, I'd be tempted to overload the thing. Empty weight and max gross weight are less than the minimums required for trailer brakes. As nice as it would be, we're looking at $400 or so for a brake system plus wiring the controller to the MH. That's assuming the axles have be correct plates to mount the brake housings. It's been said to just leave the extra stuff at home. Problem is, once we leave, there is no home. I'll be living out of the rv for 6 or so months before I find a new home. I'm not even sure at this point where this new "home" will be, so shipping it forward isn't an option. I'm looking at the garmin wireless back up camera that connects to the gps. Ive got one hard wired from the back of the HM to the stereo in the cab. PIA to get it all wired, not sure I want to deal with that again especially with a connection at the tow hitch area. The whole thing is for carrying bulky items that take up all the room inside the MH so I'm not tripping over things for the next 6 months or so. That and easy access to the bikes so I'm more tempted to use them than try and drive around town in the MH.
