Young FW full timer needs a new rig 4 months out

Thank you all for your guidance. I do appreciate it. Wr definitely did not do our research when we first jumped into it. So many mistakes were made its crazy. I bought two gassers before I realized I needed a diesel - don't even get me started on that one. Haha! We have found the rv we like. It's the Grand Design Momentum 385TH. And yes, we will be using the garage for our fur-babies. Our keystone is not rated at AL for full time use let alone a couple weeks during the year lol!
