Before we purchased our RV we rented to see if we liked "Camping" and to get the hang of operating all the gadgets, dumping, filing etc.
I would suggest a campground with full hook ups since you will have your family and tanks can fill fast.
We rented from a local dealer and took the extra insurance. We never used the generator so there was no extra charge for hours on the gen. We also had a smoke/pet free RV. If you bring pets there may be an extra charge.
We were not allowed to tow, but the dealership let us attach out bike rack to the tow hitch.
Ask about their roadside assistance in case of problems. Before you leave the lot, they will give you a walk through teaching you how to operate everything on board. Don't get overwhelmed, if you have questions once you get to your campsite I am sure you fellow campers will gladly help you out and answer you question. Have a fun trip!
