I believe the electric motors are sealed. There was a video of a Tesla driving through deep water and it started floating. Come to find out that the motors are sealed and nothing happened.Yes I will agree that the frontier has overhang but with the 6 foot bed you end up with less than 2 feet over hang and dont have to worry about snapping an 8ft sheet of drywall, a 4 foot 6 inch bed you have 3 1/2 feet of over hang. To me, as a person that uses my truck as a truck, that means i have to put flags on the end as its over 3 feet overhang and then I have to worry about the board cracking/ snaping. Which means more work/materials for same rate.
As for the off road specs posted, it would be interesting to see the durability of it all long term. The elctric motors and water kinda scare me. But hey electric cars seem to be doing fine in the snow and salt of winter.
