OK - regarding the battery drain issue... I'm really considering the solar panels on the next one. That "should" keep the battery charged in storage, correct? Also, some of the units I've been looking at go 'inactive' after a period of time and will activate upon movement of the trailer. Also have a 'geofence' setting that allows it to be set to call me if the camper moves outside that geofence area. Prices are running in the $400 - $500 range. Kinda pricey, but I'm beginning to think that may be our best option. I'm not sure I trust the wheel boots after reading some of the other threads, and the "good" ones are comparable in price to what I'm considering.
BTW - I've started a website for our wonderful Boston, Winston, who died unexpectedly a week before our camper was stolen. I will be trying to update it regularly. If you feel so inclined, there is a video I made posted there - just click on the video link & make sure your sound is on. Winston loved everybody and loved attention from anyone. The URL is:

Keep the ideas coming,
