As ktmracer pointed out, your choice of amp rating depends upon your RV's electrical system, its components and their current draws. If you have a simple, basic system with no "add ons", I would suggest installing something in the neighborhood of 100-125A. With higher demands, you should be considering 275-325A and there are several marine-type switches such as Perko, Blue Sea and others that are available.

Any Perko or Blue Sea switch you get is going to be heavy enough. They're made for the marine industry and that covers handling starters for gas and diesel engines as well as power distribution systems.

On my Laredo I used one similar to this from Canadian Tire. 325 amp. Mounted it on top of my battery box.

Would this stop me from installing a battery cutoff switch...no way! But always remember to set it to the ON position before towing the trailer. Sometimes Stuff does happen!
It should be direct wired to the battery. It does you no good if you do forget to turn the battery switch on.
