I've had my jeep for 3 years now & have a 'few modifications' to it & this is me playing!
Changes made are to engine, wheels, axles, transfer case, suspension, rear locker, rear disc brakes, armour, snorkel, winch roll cage, harnesses, etc, etc.
I've seen a picture of an Icelandic Suzuki 410 with 44 inch tyres on! - mine are only 31's - standard are 26!
It does get on the plane quite quickly!
no idea how fast yet though.
I don't have a clue about the type of hull design on my boat - does anyone!
