2004 Salem LE 28BH weight

[mctruck]

My wife and I bought our first TT last summer. Towed it mainly around town to local campsites getting the "feel" of things using our V6 Mountaineer. We quickly learned that if we want to go more than 50 miles from home, we're gonna need a bigger TV. So, that brings me to my question, All the info I have on our trailer says it's in the neighborhood of 5300lbs dry. We upgraded to an Expedition EL with the HD towing package. Took it out last weekend for the first time and it doesnt seem to be pulling it as well as I had hoped. Does anyone know whereI can find info on our trailer so I can confirm the weight and, is there anything that might be adding to the "empty"weight of the trailer that I'm not conisidering?

Thanks
