You need to regear and get a programmer with custom tunes, or trade the truck in on a Ecoboost.
You sure the trailer brakes weren't dragging?
Yes I checked the trailer brakes (actually crawled under to smell them and see how hot they were) and they were fine. I dont really want to regear if I am only going to tow once in a while.
Guess what I was asking (and has been answered) is the basic F150 isnt great for towing heavy trailers in a stock configuration. I have 33" tires that are a bit larger than stock so yes, that could have sucked some power. And as long as I had a decent run at a hill I was fine. But if I got behind a truck (like others have said) I was pretty much toast. I couldn't get going again.
I need to take the truck in for a recall notice (airbag wiring harness thing) so while I am there I will have them take a look. I have a K&M Cold Air I need to put on (gift that has been in my garage for a while) so that will probably help in the future.
Thanks everyone! You answered my question.
As for those who recommended getting a new rig .... would YOU trade if you F150 if it only had 30k miles and was paid for? <grin>. I love my truck. I live in Vegas and the sun has destroyed all the plastic but I would rather spend $2k on new plastic than $47k on a new rig. :-).
Oh, one other thing for those reading this - I will be posting another thread for a broken receiver on my hitch package to give a heads up. You wont believe it when you see it. I had three RV service guys, two mechanics and three welders saying "I have never seen that break like that in a receiver on a hitch before". Be careful when you hook up a trailer and always check the receiver hitch for a break. I cant believe mine was the only defective one and if I wouldn't have noticed it, it could have been a disaster.
Thanks again. Great forums.
