Keystone Bullet - Is it really lighter than everything else?

We have a 2014 Bullet 285RLS, the body is 30.5 ft long and weight is 5650,tongue weight 650... That includes propane and battery, but not WD hitch which weighs 100. We pull it with a 1997 Expedition, 5.4 V8 which is same frame as F150 and it pulls fine. We have used it one season and it is top quality! Have not had a single thing go wrong or not work. Have also seen only positive reviews on this sight on Bullets. So I agree light doesn't have to mean poor quality! Buy a Bullet!
