Again do not rent this vehicle if you cannot operate a manual transmission very well.
Do not get the vehicle stuck somewhere and leave it. You will be responsible for vehicle recovery and any damage incurred. The vehicle has a snorkel, this does not mean you can drive it in water. I have no idea if it works or not. Please do not test it. Please do not drive it in deep water. You are responsible for any damage incurred.
I want you to have a great trip and there are tons of local trails to explore without needing to worry about deep water obstacles. So, please don't think I am being harsh, I just want responsible renters with realistic expectations and want to keep you out of bad situations in the backcountry.
