I have a Camper (just couple of little mods and the kitchen sink) that weighs about 500kg or around 1,000lb and the Rocket tows it with Ease, I just have to be aware of it being there allow extra time for braking etc, as wrecka mentioned I have a magnetic retardation system which eases the pressure needed by the bikes brakes these can not lock up so will not cause a jack knife I have also fitted the same system to Mals (
@The Kiwi) camper it is reasonably easy to do as long as you are a reasonably good welder as there are some exact lining up to be done with the mod.
My first advice thou would be to make sure you have a Good Secure Towing Hitch and if you have not towed before borrow a smaller trailer first and get used to it as Campers are much larger and really should only be towed by someone with experience at towing, I say this as when going in to and exiting service station driveway the action of transitioning over the bumps and change in levels can make the trailer try and rear steer you if you are not ready, otherwise as long as your 360 degree coupling is kept properly lubes and spins freely all should be good. I ride at much the same speeds as I would otherwise out on the open road but use extra precaution around built up areas where Tin tops can come out of nowhere.
One last piece of Advice is that Loading the Camper or trailer has to be done properly so as to keep at least 15 - 20% of trailer weight on tow hitch and have good quality shocks with good damping in them to prevent the rear wallowing on after hitting a bump in fast sweepers or otherwise (probably more sensible) ride slower and with more care to avoid bumps in corners and sweepers, but good Shocks will make the whole towing experience better
