I see there's some new price changes on the home page. One change, E450 is now STD on all models except the 2100. I had my 2018 2400 on E350 chassis weighed, total weight was 11740 lbs, that was with full water, fuel, and black and gray tanks partially full. Front was 3400 (light) rear was 8340 (near max). Add 180 lbs tongue weight for boat and I'm 20 lbs over. I have the sag in the rear. I debated whether to get the E450. Mine rides really well, I don't think I'd change.
