I put solar on my TT 2 years ago so I'm fairly new to this as well and certainly no where near an expert. However I've asked ALOT of questions over the years and these are my thoughts.
I went with a packaged Renolgy system off of Amazon like this:
https://www.amazon.com/Renogy-Monocr...9&sr=8-2-spell
It works GREAT, very easy to install and is expandable up to 400 watts).
I was told by several people that a "smaller" system (i'll say under 400 Watts) will see no benefit from a MPPT controller. PMW is more than adequate. So your paying a lot extra for nothing.
I can not comment regarding the flexible VS rigid panel as I never consider the flex panels. One other thing I did "hear" is the flex planes are more susceptible to heat as there is no airflow underneath them and heat can effect the performance of the panel. Just something I heard, not confirmed.
Also, you need to decide if your going to put in a transfer switch so you can use all your outlets or are you just going to mount an inverter and plug directly into that?
We just pulled the trigger on a new 2018 Thor Outlaw 37RB last week. Taking delivery of it on Thursday next week. I had the dealer put in a 270 Watt system with 30amp charge controller. It was expensive to have them do it for sure! However, while the idea of drilling into my travel trailers and running wires through closets cutting holes along the way did not bother me too much, the idea of doing this on my brand new very expensive MH made my stomach turn
Good luck with your solar project. The one thing I can tell you for sure is you will not regret it. Best decision we ever made.
