Need truck advice

Been lookin for a nice truck to pull my car and trailer for almost a year now and like most of everyone else here on the forum I want it at a very good price. Of course most of the trucks I look at have door, wheel well or rocker rust and I dont want a rust bucket. SO the search has been long. Today I found what I think is a good very minimal rusted truck and to make it even sweeter its a dodge. 2002 quad cab, automatic with cloth interior but very clean. The only rust I could find was on the pass frt door at the seam and the drivers door just behind the rubber seal at bottom. Neither is bad and I think will clean up with a little Mar-hyde then can be touched up. I was under it and body mounts are spotless, the rear wheel wells still have paint on the inner with no rust. It has been in an accident at some point because the full cap has some over spray on it. Also the right front upper control arm has been replaced at some point and both hood cylinders are gone which would leave me to believe it was hit on that corner. It has fairly new tires all the way around with 11/32. Interior needs a good cleaning but no tears anywhere. Front drivers seat could use some new lower padding but even thats not bad. My main concern is will it pull my car and trailer with its 4.7L. It has 3.92 gears. I am estimating total trailer package to be around 5000 lbs or less. The chart I found on internet says its curb weight is 5200, towing is 7150 lbs. My longest trip would be about 175 miles on highway (mostly flat) but 3-4 times a year about 50 miles to drag strip. I know it wont be loaded with power but its almost to clean to pass on and the price is almost $1500 below KBB. I havent driven it yet since he wasnt there when I looked it over and I am scheduled to drive it this weekend. Here are a few pics of the truck please let me know if you think there are any reasons i should pass on this.
