Answering "How Much" Questions

I'm the guy you wrote the post for. I'm looking for a 5th wheel that a F150 can tow. For a little backgound we are looking to upgrade from our current camper which is a converted 6x12 V-front cargo trailer. Nothing special but has worked well for the last 5 years. The Scamp 19ft 5th wheel sounded good to us. We couldn't find a used one to look at so we drove up to the factory in Backus, Mn. to look at one. Nice people and very helpful but in the discussion about what truck can pull them the salesman said the one we had just looked at had about a 3000 lb dry weight. Whoa this is a long ways from the 2100 lbs in the brochure. 2100 lb doesn't include refrigerator, battery, bathroom, ect. But we decided to look for a used one anyway. However as we scouted online we found several 18-19 ft traditional 5th wheel trailers from the 1990's that are considerably cheaper than a used Scamp. From what I can tell from various online sites they have a appox dry weight of 3000 lbs and a gross weight of 3800-4300 lbs. If I am reading your chart right and the online calculator linked in one of the posts my 2001 F150 would be right on the border of safe giving no margin for safety. I took the 1500 lb cargo weight and subtracted me, my wife, 2 dogs, hitch, fuel, and 100lbs assorted stuff and came up with just under 800 lbs. 4000 lb gross trailer weight would have a 800 lb pin weight at 20%. Hopefully I missed something in my calculations and am wrong because if not that would make almost any 5th wheel impossible to safely tow with my F150. As I said in the beginning of my post I'm the guy you wrote the charts for. Either they are clear enough for a dummy to understand or you have your first dummy that couldn't understand them.
