Ragoodsp, had it right when he said "I hate to say it but I think you are going to be surprised and not pleasantly so, The Cat's will tell the story."
I just returned from the CATS scale near Lockhart, TX and sure was not pleasantly surprised. Front axle 4440 lbs and rear axle 9320 lbs for a total of 13,760 lbs; max capacity for the E-450 is 14,600. Just me in the coach (6' at 211 lbs), full 55 gallons of fuel, less than half tank of LP, 15 gallons of water, empty grey/black tanks, fully equipped kitchen but zero food, lightly equipped bath (4 bath towels, 2 hand and 4 wash clothes), one set of bedding for the rear queen bed and one set for the sofa bed, two light lawn chairs, small tool case, and a few odds and ends. No clothes, computers/phones/chargers, DVD, video games, reading material
Must add the wife and two young grand kids which I estimated at 250 lbs; she refuses to divulge her weight. Plus tow bar and toad hitch weight at 500 lbs. Food and incidentals estimated at 150 so I'm overweight. I know I can throw away the bedspread and throw pillows on the rear bed, rearview mirror on windshield (loss of compass and thermometer), old Rand McNally Atlas and buy my Irish whiskey in half pint bottles instead of the gallon bottle for a weight savings of 10 lbs. If wife and I lose 20 pounds each we have saved a total of 50 lbs but the coach is still over weight.
