I think I'd rather have my truck at this point. The cost per month is crazy for a new truck and I don't see that much advantage.
I'm at a crossroads:
I can keep the truck bone stock and spend $2,500 on an extended warranty to 200,000 miles.
OR
I can spend $2,500 on modifying the engine to run right improve mileage, but void my warranty.
OR
I can do nothing, let the factory warranty run out in 1+ yr.
I would love to add a Banks brake. My service mgr at local Ford dealer doesn't think that would be a problem with warranty as long as I remove it, but doesn't want to see anything that adds power or removes emmissions.
