I am so glad I found your thread. I have a 2026 252rl and have already put in one 300ah battery and getting ready to start he purchase of the other items needed to add the converter. Looks like the only major change from your trailer to mine is they did install a 400w solar pane on my roof. I am guessing I will need a second panel down the road. I will also add a second battery. I will be using a Victron multiplus 12/3000. If you have any thoughts or changes I would love to hear them. Thanks
