NewShockerGuy how difficult was it to pull the box. Frame doesn't look to rusty.
So in my case on a scale of 1-10 I'd say in all reality it's like a 4. I say this only because of some of the difficulties I faced. If you don't have ANY of what I mention below difficulty goes down to a 2 easily.
I have a tonneau cover. So this first had to be removed. Because it's never been removed in at least the 5+ years I've owned the vehicle I had a little trouble with fastners...etc. Once that was up I then had to remove my bed line. The ford OEM bed liner is REALLY a tight fit. Add more time to remove this.
Then came the T55 torx bolts. 4 of them came out pretty easy in the rear. Mind you I was spraying Kroil on them for a week prior. I then proceed to take the front two bolts off... Wouldn't budge. Spent another 3-4 days spraying those bolts down with kroil three times a day. Ended up buying a new snap on torx but because I was afraid I was rounding the bit off and didn't want to round the bolt heads off. Finally was able to get those bolts off. They were extremely rusty. I will have to post a picture of the old bolts. Removing the bed I was told could be done by two people. So I naturally asked my wife to help. That proved t to be useless... she was not able to lift the side at all. I had no trouble lifting my side. I asked my neighbor who then helped me move it to the side of the house. It's not heavy mind you, just a tad awkward. I also had to remove rear bumper because I have a step side bed and I could not lift the bed up over the rear bumper. Not hard, just 4 bolts but again, another thing to remove.
If you did not have the cover or bed liner, removing the bed is very simple process.
Since I have all this off, I figured I don't want to do anything again so I am replacing everything that I see. Fuel filler neck, hoses, tire carrier...etc. My fuel pump died luckily I wasn't at work in the parking garage or I wouldn't have been able to get my truck out and I'd be doing this work there, which is nuts.... and it didn't strand me on the highway. It literally died when I pulled it out of the garage backed it up and went to start it the next day. Because it's been cold/rainly I've been delayed in fixing it just because I refuse to work on it when it's 20 degrees outside. But after the pump was replaced, no issues in pulling it in the garage and now finishing the work.
Frame isn't TOO bad honestly from some of the pictures I've seen online but it's one of those things I have a chunk of body off... why not clean it and paint it along with the bottom of the bed, then I don't have to worry about it.
