Question on purchase of travel trailer.

I will give you guys a little background on myself and family. I started out as a mechanic in a garage in high school. Was a diesel mechanic in the marine corps. Security at harley davidson. Assistant manager at a coal power plant. Then in 2001 moved to NH with my wife who was from NH. Got a job as a cdl truck driver and heavy equipment operator at local town. In 2015 due to child care issues I left the town and got a job at a cnc machine shop. Work four 10 hour days then watch child while wife work her three 12 hour days as a RN. We have done many camping trips to PA to see family and friends either tent or borrowed a TT from friends for a couple weeks at a time. I do know not to believe the sales people. I towed a friends open range 310 and all the stuff they had in it when we borrowed it, he has the same truck as I and I dont know how he does it. If I recall correctly when I weighed just the trailer he was way over loaded at 10.7k. I would not want to tow that everyday! Almost forgot firefighter and emt-b from 2005 to 2013 as well.
