Welcome to the forum and congrats on the Columbus 340RK too! Most of us started off with little or in my case no RVing knowledge which changed as time went on. I'm looking forward to having you join in discussions when you are ready.
If you have questions please do ask. We are a friendly group eager to assist.
After upgrading from our last rig, a Cougar 30RLS. We decided to go bigger ( both tow vehicle and RV ) and went with the Columbus and are now " Born Again " newbies.
