LOL Glenn, yup reading all the instructions is sometimes not my strong point either.
I picked up my LED battery
monitor from Princes Auto for about $20. The display is attached to the plug with a small wire so I mounted the display on the wall near the plug with double sided tape and only plug it in when I actually need it (dry camping). Like it as it has a small alarm that beeps to let me know before the battery
level gets to 50% so I know to put out the solar
panels. A small investment but returns are big.
Another great small gift is a small wireless indoor/outdoor digital thermometer. Put the small sensor in the fridge
. The display that is also mounted on the wall tells me the fridge
temp and the inside trailer temp. Helps to confirm all is well with the fridge
in warm weather. I found one with a sensor that is only about 2" x 2" so it doesnt take up much space in the fridge and the wall display is not much bigger.
