Ride a bike - it would be more comfortable
The app is pretty useless. So don’t bother. But I would also suggest you find another RV company. Especially for any long trips. I have never had such an uncomfortable and noisy ride. Every crack in the road rocked the RV. Do not believe the pictures on their website. The RV we had was disgusting inside. If you rented a car from any rental company, you’d expect a clean and well maintained car. Well I guess Cruise America believes throwing on some duct tape here and there and using staples to hold plastic together is good enough. Walking would have been more comfortable
