before I go mudding I would like to try to make sure my truck could handle deep water and at the same time keep it a daily driver/weekend warrior keep in mind I am a big diy kind of guy the truck is a stock f150

 

PVC snorkle? But don't think other than making it a boat you'll keep water out.

Axles, tranny, transfer case, and crank will need to be drained and changed every time you sink it. Extended vent tubes can help, but that won't keep all the water out.

change all the engine trans and rear end gaskets before you go they probably don't seal like they used to and could use a freshening up. and like he said drain and change fluids
