You can go to the websites for Arctic Fox and Wolf Creek and Northern Lite and Lance and download their brochures that provide information as to which will fit for a short bed and the weight. I would not worry about the weight as it is the large 10'-11' campers for long bed trucks that are going to be over 4,000 lbs. dry weight.
Good idea to take your truck to a CAT scale and get the exact weights at each axle. Knowing the weight of the empty truck on the rear axle and its rims and tires provides a baseline. 95% of the camper's weight is going to be on the rear axle. Based on the total weight of the rear of the truck and the camper you can determine whether the truck's tires can handle the load or will need to be upgraded.
If for example the weight of the empty truck on the rear wheels is 3000 lbs. and the camper has a dry weight per the manufacturer of 2500 lbs. you will have a theoretical dry weight payload of 5500. In reality the camper is likely to weigh closer to 500 lbs. more and you will want to add another 1000 lbs. for gear, water, people, etc. in the camper which add to the total load on the rear tires. With this theoretical camper the total potential load on the rear tires could be as high as 7000#. That works out to 3500 lb. load capacity tires at a bare minimum.
Ford (like GM) have rear axles and wheel bearings that will support more than 9,000 lbs. so the possible weak points are the springs, rims, and tires. Easy enough to add SuperSprings or new rims or new tires to address any weak points. When I bought my Chevy 3/4 ton truck it came with tires rated at 3195@80 PSI and I sold them on Craigslist having replaced them with tires rated at 3750@80 PSI for a load capacity gain of 1110 lbs. at the rear axle. That provided the safe margin I wanted with my camper.
At each stage I paid the $10 to have the truck weighed. It was weighed when new, after adding the Supersprings and new tires, with the dry camper in the bed, and with the camper fully loaded for a trip.
All brands of campers have their pros and cons. Lance campers have fewer flaws than most and are better insulated than most for cold weather use. What varies with the different models are the capacity of the holding tanks, provision for 2 batteries, provision for 2 LPG tanks, availability of a slider, 4-season setup, use of interior space, setup for towing a trailer with the camper in place.
