Looks like a darned nice camper!! One thing I've carried over to camping from my military days are checklists. Make a list of everything you carry in to the camper, delete/add to the list as you go along. After a few campouts, you'll have a pretty comprehensive checklist to go by. Nothing worse than getting all set up in the boonies and find out that there was one widget you absolutely need that's still sitting on the kitchen table back home.
There are several pretty good starting point checklists online.
There probably are some owners that only had the two good days while owning one, but I've had a good day just about ever time I've used mine and as for the few times I haven't, they were all weather related, no control over Mother Nature. Not everything needs or has to be an investment, sometimes you just got to stop, smell the roses and enjoy some fruits of your labors.
