I have a 2002 and love it so far but no major pulls with it yet. Mine weighs about 14,000# gross also. I have a few problems so far but not terrible but I kind of expected better.
1) When water pump runs terrible noise like pipes vibrating inside against wall. I think it is because pump is connected directly to rigid plastic and needs 12 or 18 inches of flex pipe on inlet and outlet to fix. Probably fix myself.
2) Ocassionally pump did not want to shut of and would keep running. There is adjustment on front pump to correct.
3) Mine has triple slides and on one side 2 screws that fasten skin to angle iron broke off letting the skin flap lose. I replaced the screws.
4) Screen over dining table pushed out. I think table hit it when slide was pulled in.
5) Multiple water drains under the trailer. They just have caps on them and where they are located kind of a pain to drain after using. I have not came up with a way to make this simplier yet!!!
Next week will be toing from Phoenix to San Bernardino Calif. via I-10. The from San Bernardino via Barstow to Kingman Arizona. The I-40 through Flagstaff to our place East of Showlow Ariz. Lot of differnt pulling grades, ambient temps, etc. Let you know after that how it does. Look forward to sahing out truck and trailer on this trip.
Floor plan on mine kind of unusual. Opposing rear 2 slides for kitchen, dinging area with bar in the middle. Living room in middle by entrance door then bathroom and bedroom upstairs with slide for queen bed area.
Sorry about long post.
