We recently rented the 19' RV from this location and our experience was awesome!!! The inside was clean and perfect for 2 people. The rental process was really easy and explainable and the customer service was great. A really fun experience to rent an RV for a roadtrip!! We took it up to the Grand Canyon and parked it in Mather Campground. Dumping it on your own is actually not too bad, just remember to keep the black and gray rods PUSHED IN before you open the dump valve to put the tube in. We tried to conserve the generator use so we brought foam coolers instead for our food that had to be kept cold. We ended up only using 2 hours of the generator (which came to an extra $7--not bad!) PS: I recommend bringing a foam mattress pad for the bed, it isn't terrible but it also isn't the most comfortable.
Highly recommend--fun, clean and affordable!!
