lots of people only use their rvs only occasional. not really a problem if you take a few precautions. Gas gets stale and can gum up injectors pumps etc. Its a good idea to run all the systems every couple of months. rubber hoses and belts get brittle if not used, tires get square if sitting for a long time. Every couple of months, run it up and down the freeway a couple of times and you should be fine. use a fuel stabilizer if its going to be sitting for a long time, keep the batteries charged.
