Our recently purchased 2016 Georgetown 369XL spends most of its time at our seasonal site plugged in to a 30 amp service. (The electrician will be here on August 20 to install a 50 amp service.) I have four group 27 batteries installed by the dealer. A few times a year, we head out for week long NASCAR races and, on occasions, weekend trips to friends "outings" when we prefer not to drive home and need a place to sleep.
Of course at the friends "outings", we can run the parallel Honda 2000 generators all day and all night. At the NASCAR races, there are quiet hours after midnight in which we can not run the generators. We also take many day trips at the races and the generators are not running. With the Dover race now being in October, I am anticipating using the heat quite a bit over night. I also have a residential frig, and CPAP machine. (Providing I get a 12 volt power outlet wired up in the near future.)
So my question is, would it be advisable to install a battery monitor with my given situation? I am thinking (if needed) I would want the Trimetric monitor, model TM-2030-RV with 500 amp shunt. Most searches I have done on Google, YouTube and here talks about also using solar power. I have no immediate plans to buy solar panels. I am just trying to justify not only to myself, but more importantly to the DW the need to spend another $200.00.
We have recently experienced a few power outages with the summer storms and the factory installed idiot lights drop to 2/3 in just a short amount of time. (Yes, I know they are not accurate.)
