Hi fellow forum users. I have a 2017 Solitude 310GK which I purchased new last year and am thinking about installing a generator. Am not sure what kind to install or what size, etc., but have a friend who wants to sell his Onan 5500 and am wondering if that will work in my RV. I'm really a newbie to RVing and don't have a lot of mechanical knowledge so am wondering if anyone out there can give me some assistance or suggestions regarding proper generator installs. Not sure if I should go with the used generator, or with a new one installed by my dealer. Thanks for any help you can give me. JT
