Had an absolutely wonderful stay. Paul had the camper perfectly set up for us when we arrived and even provided dog sheets. We brought our own but it was still appreciated

This was our second time renting Katy's trailer and everything was amazing! Katy is the best host and her trailer is awesome. Her trailer is very spacious and clean. It has everything you need for a wonderful camping trip! Her service is the best from start to finish. We love renting from Katy!

Scott and Leia were great. The drop off was right on time and the trailer was set up in minutes. Everything was exactly as expected. Maybe some wine glasses could be added but that is not a big deal. Would rent again in a heartbeat !!
