If you’re keeping the truck 100% stock, there’s a very small use case for an aftermarket warranty. Like any insurance, they will automatically balk at any major expense, and hold you to the exact terms of the contract, so you will need to have all maintenance records, probably from before the warranty period begins as well. if / when a hard part or major component goes - turbo, transfer case, transmission, motor part requiring a tear down, they may not pay for the tear down or they may offer to reimburse if the repair is covered, which it won’t be unless you’re willing to fight them for a few months. Time is on their side while you’re without your vehicle.
I would only do it for a purely stock vehicle I had meticulous records for and it was NOT my only vehicle to use. That way, you can negate their main tactic: Delay, delay, delay.
Ford’s ESP is much less of a PITA to deal with.
