I will say if you do use a 3rd party warranty. Make sure you are calling them if your truck goes into the shop and keeping up with them as to what stage the shop is at and if its been approved. they will look for the slightest reason to deny your claim. i learned this lesson at the cost of 8000.00 dollars out of my own pocket.
Had one from arrow truck sales. Totally crap. They say you only pay $500 that's bs. They nickle and dime you on EVERYTHING! Fluids gaskets bolts. You name it. Had a oil cooler done. 1 day job rigjt? With my warranty it was a week job cuz of all the #### plus alot of $$$$ cuz they only pay so much per job
