I just bought my F150 5.0L 4wd with towing package. Few months back. You can download the Ford towing guide that lists towing and payload capacities based on truck body, engine, and gear ratios. 2wd F150s are rare in my area, too. Get the factory towing package to get the better rear gear ratio. Better yet would be to get the Max Tow package or the HDPP Heavy Duty Payload Package to get the even better ratios and/or bigger heavier duty differential. Both of those packages come with a larger gas tank, too, a consideration when towing a heavy load and getting half your unladen gas mileage! I got the 4 door short bed. IF you think you might ever consider a 5th wheel, you'll need the 6.5 or 8' bed. The HDPP is required for truck campers per Ford.
