My first trailer and plans for solar

Good info everyone, I definitely over estimated my water consumption and capacities. Will def. do a Navy showers. Also, my 3.4L tacoma struggles to pull on the freeway, so Im hesitant about sinking a bunch of $$$ into solar until I know that I'll keep this trailer longer term, I honestly did not realize the size of the investment for solar (cash, research, install etc) so a small generator, though not optimal is what I'll use. My boss said I can borrow the 4000W gen, so I might just take that. After this trip I'll know a lot more about the trailer and my preferences as they relate to available options.

If you have any other thoughts, I'd love to hear them. I can tell a lot of you are very knowledgeable and experienced, thanks for sharing with me.
