How to measure how much solar we need?
(hope this is right section) Brought home TT last month and now have basics taken care of and RV is road ready. Now starting to think about bigger long term projects. One project is, we would like...

We have six x 235 W panels (1.4 kW) with about 9+ kW-hr of LFP. I wrote that we could conceivably emplace another 3 x 235 W panels for 2.1 kW. We have not found a reason to do this but we could run the AC on 2.1 kW of panels without utilizing the battery bank.
40 Ah is only 600 W-hr. You could conceivably get 40 amps at 12 V from a 700 W panel.
Our max power was 1.3 kW this summer. The most we get this time of year is 0.93 kW. The panels are ganged in two series of 3 x 30 V (235 W) panels. The voltage is thus 90 V to controller from the two gangs in parallel. So 1300 W was only 14 amps.
Our grandson changed out the charging pin so that we had a direct link to the backup video without hooking/unhooking another cable. 120 W at 12 V from the pickup's alternator is ts to the 500 to 1300 W from the solar.
