Unless I missed something here, where do you come up with a hitch on a vehicle being rated at 5,000 max tow rating? If you are talking about a truck without the tow package, then okay. Ford says that towing in excess of 5,000# requires the tow package (pre-2009 trucks). There is now way on this earth, or anybody elses, that a truck rated at 9,200#, like the 2008 F-150 Supercrew 4WD will have a hitch capable of only 5,000#.
Like I said, maybe I missed the message somewhere, but clearly the trucks tow ratings will have a hitch to match, unless the hitch was installed aftermarket.
On to the OP...
I run a trailer at about 7,000# loaded. My 2008 F-150 long bed Supercrew has the 3.73 L/S rear, and the 5.4L. I have strictly driven diesels for about 10 years. Yes, it was a shock when I pulled our trailer for the first time, but once I realized the trucks potential, I see no need to run out and get a 3/4 ton again... especially with diesel prices and the V-10 economy.
Look up my posts and see what I have posted. See what Welfare Wagon has posted, too, in the towing section. I'm waiting with baiuted breath to order my 2009 in a few months just because the 6-speed will amke a big difference. I'd certainly not change gears or anything - especially since you are within reason -and tow 20% of the time. I am like you, but I drive 50,000 miles plus a year unloaded and not towing. My Supercrew is a much nicer ride for daily use, and I have not yet regretted towing my trailer to the point I've had to run out and look at a Superduty again. And, my blood still smells like diesel and I leave soot stains in my underwear.
Mind you I did change trailers this fall, too, and the trailer alone has made a MAJOR DIFFERENCE! See the "What are you towing" post in the towing section for details.
