I like the display on yours better than our Oregon Scientific. (It's a LaCrosse Technology--good prices, too, at your web site.)
We got ours primarily to monitor the refrigerator temperature. Since then, the frig is never too warm and we no longer experience the dreaded ''frozen lettuce'' syndrome!
But I do plan to get a second remote to attach outdoors. As you do, we take the base unit into the tow vehicle when we're on the road. The units attach firmly with velcro.:thumb
During the winter, we bring the base unit into the house, and leave a remote in the Casita
Rick, I would order an extra remote in addition to the remote that comes with the base package.
Also, Wallyworld has carried a couple of brands of these over the past year or two. The feature that I did not like about WalMarts was that the buttons (to change the channels) were on the back of the unit. If attached to the wall they would be inconvenient if you wanted to switch the channel being displayed (like from refrigerator to outside air temp.)
