Please help me with solar setup
I have been reading a lot about solar on here and finally decided to take the plunge or come to the dark side as some would say. Sunny side makes more sense, but whatever. :) We do not use a lot of...

I am in the Northeast so mostly sea-level. Mile high is basically out of the question.
Niner, what charge controller are you using?
I adjust the PV off voltage to 14.8V and then to 15.0V for bulk and top off charge, and to 16.0V with battery disconnected from everything else, for equalize charging of my battery. It works, quite well I might add. For Flooded Lead Acid batteries ONLY, I run a Trojan T-1275 150ah battery.
This is a picture of me equalize charging. V requested for cut off is 16.0V. Reading at the top, the 15.7V, is the reading of the voltage at the battery. You need 16.0V AT THE BATTERY, before you shut down Equalize Charging mode, and reconnect the battery to the RV, for a complete equalization charge. In the beginning, when you first start doing EQ charging, you do need to baby sit it, until you figure out approximately how long you need, time wise, to do an EQ charge session. Mine can take from 45 minutes to 2 hours depending on how much depleted usage for how long, in days. YMMV. Doing top charges daily to 15.0 to 15.3V helps cut down on the frequency of Equalize Charge sessions necessary, by getting the battery almost completely fully charged daily.
I don't believe in 50-90% SOC charge for weekends, or for a whole week... I want 98 to 99% SOC DAILY, if I can get it. Keeps the battery in much, much better shape.
