Hitch,LED,and Layout plan

[loadmaster]

Ok; everyone I'm new to the Montana world, but this is our fourth camper we have owned. So I'm not new to the camping world.
Here is my question to everyone, I'm trying to find out if I can order a rear hitch for my 3582RL camper or do I have to make one. I'm looking because my wife and I ride bikes and I would like to haul them on the back of the camper and not in the bedroom on the bed.
Also has anyone replace the rear stop light and turn signal light with LED lights. The incandescent lights are nice but I like the new LED light better I think you can see them better.
Also can anyone tell me when I can find a layout of the tanks under the camper, I would like to learn everything about this camper as possible.
Any help would be greatly appreciated.

Thanks
