Our primary focus over the past week has been learning to manage our power consumption and battery charging. We have not had another episode of dead batteries, but we’re very diligent about manually checking the voltage on the batteries several times a day. Andy is still convinced that they are not holding a charge the way they should, even though they are brand new. But without any prior experience with boondocking, we don’t have anything to compare it to.
During the day, we hardly use the lights, so the only things that should be drawing on the battery are: (1) the CO2/propane monitor, (2) the water pump, (3) the thermostat in the refrigerator which runs on propane while boondocking, and (4) the backup camera monitor and dashboard display. My guess is that this last item is the one that is creating the greatest draw on the battery, but there’s no way to turn it off unless you just pull the fuse or disconnect the wiring.
Before the batteries went dead, we were running the generator for about an hour in the morning and an hour at night, and we weren’t testing the battery voltage. Now we’re finding that we need to run the generator at least 90 minutes each time. If there is any significant power draw on the generator while it’s running (i.e. using the Instant Pot or the microwave) then we need to run it longer in order to top off the batteries. That means more gas is being used at the rate of about 1 gallon for every 2-1/2 hours of generator time.
On Friday we drove to Phoenix to pick up our solar equipment, which we had had shipped to our friends’ house. When we got back to the rig and unpacked everything, we had three solar panels, the Kodiak portable generator, a 30′ solar cable, and three LED outdoor lights. Unfortunately, we have not yet received the two chaining cables to connect the three solar panels together (these were supposed to be part of the kit), or the car charger to charge the Kodiak while we’re driving (not part of the kit). Andy is going to contact the company first thing this morning to find out when we can expect those items.
We were able to connect one of the panels to the Kodiak and test it out, even though it was pretty overcast this weekend. But we really need those chaining cables and a good sunny day to see the real potential of this system.
Yesterday we drove into Tucson and went to Home Depot where Andy picked up some PVC pipe and fittings to make supports for the solar panels so we can stand them up and lean them at the right angle to get the most sunlight. He’ll be working on those this week.
On Saturday we drove to Eloy again to refuel, dump the tanks, and refill the fresh water tank. The one downside to this boondocking spot is that it’s not really close to a dump station. We drove 64 miles roundtrip to take care of this little bit of housekeeping. The rig gets about 8.5 miles per gallon, and gas cost us $2.60/gallon, so it cost us about $19.58 in gas, plus the $8.16 dump fee at Flying J, for a total of $27.74 to dump the tanks and get fresh water. (Flying J charges $12 to dump and get water, but we get a discount with our Good Sam’s card.)
The exciting news is that we went SIX NIGHTS this time without dumping! That’s a new record for us!! We have never really pushed it to the limit to see how long we can go. The last thing I want to happen is for the black tank to fill up in the middle of the night. YUCK!!
Technically we could save a little money by driving back into Tucson to the free dump station we found two weeks ago, but the hassle of driving in city traffic offsets the small savings. Alternately, we could go to the nearby state park and pay $15 to dump and get water, but we would still have to drive somewhere else to get gas and propane, so we just prefer to drive a little further and take care of everything in one location.
It’s hard to believe we’ve been camped here in the Cactus Forest for almost two weeks. We’ll be pulling out on Thursday, headed to an RV park in Glendale, Arizona for Christmas. While I’m looking forward to having full hookups again, I’m going to miss the peace and quiet and wide open spaces of our boondocking spot. We’re already looking forward to heading further southwest for the new year.
