My we are a helpful bunch aren't we. Most RVers are more than willing to help you out so when you do rent a trailer and hit a campground don't be afraid to talk to folks. We love to talk about our trailers and trucks.
We started into the RV way of life going into 7 years ago now and I am on my 3rd trailer. 1st one was 24 ft. Great learning unit. Next was 30 ft. We went on the big circle tour out to the Olympic Penn. and Grand Canyon and points in between. We now have a 37 ft and its by far a handful. Pulls just fine but I have to look very carefully for a gas station I can get into and out of. The 30 ft. one was no problem really for that. Length will limit you on some state/federal parks you can fit into also.
Backing a trailer is dependent on wheel base. The shorter the trailer the quicker it reacts to steering wheel input. Longer trailers are easier to back up. Its not hard to master it but practice goes a LONG way. Don't go get a small U-Haul and think it will be the same as a bigger trailer. Get the longest one they have if you can or at least similar to the trailer you will actually rent to camp in then it will react the same.
Getting to where you are going is half the fun of the trip. Never be in a rush. We try to stay off the interstates and do secondary routes as much as we can. Lots to see in small town America so don't be afraid to stop and see things.
Enjoy the learning process. Enjoy your future travels.
