Welcome to the forum and the Montana family. One thing we all do, myself included, is look at things from our own point of view. How you will use your camper will go a long way toward determining places and things. Some things are universal. Get some good, quality outdoor chairs. My wife likes her GCI rocker, I have a directors chair. An outdoor mat of good quality is also useful. You will also find an outdoor weather station useful regardless of how you camp. We have wind/rain on ours as well. If you will do a lot of boondocking, you may want to look at LiFePo batteries. You may also need a good generator set. We spend a lot of time in our Montana, so we have Instant Pot, Coffee Maker, Cappuccino and frother, immersion blender and dishes that stay in our rig. We duplicate the same brands as in the house. We use a Mopeka propane monitoring system as well. Enjoy your new journey.
