Brett is an amazing host, and the experience greatly exceeded expectations.
Brett assisted with the hookup and went above and beyond to get us going. The towing was extremely easy, but recommend a truck if you're going to be taking it any distance. You'll also need the circular wiring connector.
The RV itself was amazing. In my opinion the photos don't do it justice, and the set up is perfect. Brett configured us for dry camping with no hookups, and everything worked exactly like you'd want it. The batteries give you a bit of power for lights and fans if you don't have the generator going, and the generator was very easy to hookup. We didn't need to use the AC, but it seemed extremely good. The generator Brett has as an addon for the rental was very nice -- small enough to move around easily, and it has an electric start, so no pulling required.
The bed was very comfortable and long enough for a 6'2" guy. Everything was clean and well maintained, and all of the chocks/cables/hoses were easy to access. We also didn't end up using the bathroom much, but it's a full shower/toilet and was much nicer and larger than expected. On a longer trip it would work great. Small detail, but the blackout shades were amazing for sleeping in.
I highly recommend considering this option for your RV rental -- don't be put off by the teardrop shape, it's very roomy inside, extremely modern, and it has everything you need for a great trip. I wasn't towing it for a long distance, but I imagine the fuel savings due to the streamlined shape would add up. I will absolutely be renting again the next time I'm in the area.
