All Tomcars can ford depths of around 1m with no problem. If you are going to ford deeper depths, we recommend you install a snorkel on your vehicle.
Do remember though that the Tomcar is not an amphibious vehicle! Take care when crossing streams and creeks - always check the depth BEFORE you drive across. Note the direction of the current and keep momentum whilst crossing.
