I'm considering adding solar to my RV to run basic stuff, not worried about A/C or large load stuff. I do have Directv and a LCD TV. The fridge can run on the propane. We do some dry camping at rac...

As PT indicated the appropriate solar system paired with the appropriate battery bank is highly dependent on your intended usage. The spreadsheet provided in PTs post is an excellent resource for initial sizing estimates.
Since my guess at your intended use appears to be close to what I use mine for my system is listed below just for reference. I mainly use mine for college football tailgating generally meaning 3 days and 2 nights without any hookups and using multiple HDTVs with satellite for many hours every day
- 265 Watts solar 12v nominal panels
- PWM Morningstar Prostar controller (upgrading to a 20a MPPT Landstar controller shortly as a guinea pig for this forum group)
- Twin 6volt Trojan T-105s as a battery bank rated at 225AH at 12volt
- 600 Watt PSW Inverter with auto switching to desired AC circuits
- No Microwave use (Inverter is not large enough)
- Most used lights have been converted to LEDs
I can easily do the long weekends without going below 80% DOD and generally stay above 50% DOD depending on weather conditions.
