hi - post pics of this ride when u get it - POIDH and enjoy the new ride - awesome!!!
open ended question - how deep are these creeks on average? 1', 2', 3', 8'
it will be the measurement from the tape measure from the floor underneath to the ground - the owners manual will also give you a number in inches.
my advice is to search p-1000 snorkel online - there will be numerous ones available
the snorkel is only necessary when you are in up to your ass and wishing you had one
maybe also u-tube p1000 snorkel\water crossing and do some self education to learn what others are doing - these are expensive toys - hate to see someone think its a u-boat (and it can be)
