Robert was a pleasure to deal with. He was on time for delivery. He went above and beyond to fix a water pressure issue and brought the table that was missing for camper. The camper was clean and had the essentials that were noted in the ad. If you have kids and are planning to use the DVD part, bring your own, as the selection is small. We would gladly rent from him again.
