Check avatar, had Safari snorkel fitted and have been in water up to bottom of glass.
Advise you remove all carpets, and seal the removable plugs in the floor pan front.
Have sat in water for 30+ mins with water above wheels and only 1/2 inch of water entered in passenger side only.
Biggest problem was the alternator belt slipped off pulley but that could be that i hadnt tightened it correctly.
Other than that you wont be dissapointed.
Oh and get some mud terrain tyres fitted.
