This coming summer we plan to park our camper at some property we own and use it for extended stays; perhaps as long as a few weeks at a time. However, the camper itself will be at the property for most of the summer as we come and go. For those of you that have done extended stays or use a seasonal campsite, is there anything special we should think about for this type of use?
We've taken our 21BHS out for several 1 - 2 month trips over the last three years. We also stay locally sometimes a month at a time with a couple of weeks in between stays.
The first long trip we made, we discovered that our A/C (the original Penguin 2) could not be trusted as it was freezing up. We replaced it with the A/C from RECPro (which I believe you already did). The big benefit from that change (aside from the fact it is a nice and quiet A/C) is the heat pump. We never realized how handy that can be on a long trip.
The other thing that makes a difference is the dehumidifier we bring along. I store it in the back seat area of my truck and then carry it into the camper and plug it in near the slide area. Works great, keeps the humidity down and also prevents any musty smells from taking over.
Other than that, the camper has been great as is for long trips. How is your mattress? That would be the only other consideration I can think of.
