Eagles are Jayco's top of the line TT, so you should not have an issue with trailer if it has been maintained. check for leaks or past leaks carefully. On a real estate website, a comment was made that if a house smells like frou-frou candles or air freshners, then it is probably covering something up. I thought that was a great hint for used RV,s too. Use your nose to warn you of anything that is not right. If smells are just from being shut up or use, clean and put outside in the sun for a couple of days to help. (My previous TT smelled like cat (not urine, just cat) and closed up smell and everything went outside for a couple of days if it couldn't go through washer-- mattress, cushions, valances, etc and that made it smell fresh)
I agree with the others that you should be okay, if the weights advertised are right. You can check with Jayco, if you want to verify (or cant read the stickers on the trailer).
check out the fridge because I would guess that is the appliance that is most likely to give you problems. once you get it, clean, treat and caulk roof as soon as possible and you will have a good trailer to have lots of family fun.
