We rented RV for 9 days, wanted to visit national parks, after we started moving, half of the drawers opened and this lasted until we bought a tape. Previously we believed RVs must have had good locks for safety reasons, but only some of them worked property so we nearly lost our laptop...
The staff kindly informed that the indicators of water and battery were little bit out of order, but first , unexperienced, we thought that was not much of a problem. However, it turned out to be essential.
So we arrived to the first fairground and wanted to make beds, but when we touched them, the mattresses turned out to be so dusty that we had to beat them up outside the vehicle. In case we had asthma or something they would be quite a challenge to sleep there. Anyway, if you charge $210 preparation fee, can you vacuum mattresses? No?
The walls and floors also needed some washing, so we did all that before bedtime.
The batteries turned out to be old and thus dead and in case you don't know in Yosemite and other parks (where RVs are useful at) they don't have full hook ups..so even economising, not turning on lights and freezing we still soon had our fridge off, so after just two days in parks we had to leave this idea and go to more civilized places because even 5 -hour driving would not help to charge the RV battery.
While dumping the water we had a leaking hose and you know, the check engine light went on on our way back. Don't want to be too precise with details, but I guess that was a trip that we didn't want.
Anyway, we addressed to the company on our way back, they said they are really sorry.
Fine then. We are very sorry for the feedback.
