Mine's fine w/o bags. 2005 F250, ext cab, diesel.
Camper is 8.5, trailer weights 7000, probably 700-1000 on the tongue.
Ford trucks starting about 1999 are rated far higher than the old "one ton" and "3/4 ton" ratings of old.
My f350 (year 2000) has a payload rating of almost 3000lbs in the bed! In 2005, they bumped it up even higher, and then again for the latest trucks.
Also, remember your TOTAL COMBINED WEIGHT RATING. This is your truck, camper, and trailer combined. On my truck, its 19,500lbs.
My truck weighs 8000lbs with fuel and driver. That leaves 1900lbs of legal payload (my gvw is 9900lbs). That means I could haul a camper of 1900lbs and thats it, or a camper of 1000lbs, and a trailer of say 9000lbs with 900lbs of tongue weight. That would put me at 8000 + 1000+9000 = 18,000lbs. Fully legal.
Good luck finding a 1000lb camper with all the options tho.
Weight really only matters during an accident. If your insurance finds out you were over legal, you could be denied coverage. Very few cops I know of check private rigs for weight violations, and even fewer scales....unless there has been an accident.
