I shall be a complete RV novice and to be frank quite apprehensive.
I understand where you are 'at'. Reading up on RV's on-line can be quite daunting first time, but once you have a general idea of what to expect from researching and then being 'shown the ropes' on collection of the RV, it really is quite straight forward. Once you hit the road you will adapt quite quickly, just don't give yourself too much to do in the first couple of days of driving. Collection can take time, the paper work and getting shown around the RV [Possibly, have to watch a video] before getting going, so keep that in mind when planning your first stop. We then like to stop a little way up the road and check everything is 'travelling' OK and to get vital supplies, [tea bags for the wife and beers for me !] food, fluids, bathroom 'stuff', logs and fire lighters etc, so that we are 'independent' when we arrive at the campground.
