Good for you! Just in time for the season. Take your time and look it over very carefully and become familiar with all systems. We, like many others, developed a checklist for-before leaving (like ensure full propane, turn on refer 24hrs ahead etc), pre raise checklist, pre lower checklist.
As a past camper owner, I'm sure your up on things but the Hi Lo is just a bit different.
Welcome, by the way!
