AFAIK, the only thing Don is wishing he could have - with his solar - is A/C. This takes a lot of solar. Water pump is a minor item of energy budget, anyone who monitored their usage would know. Water heater is typically on propane, when off-grid.
The bulk of DC loads (without inverter) are fans and propane fridge circuits. Maxxair - as I recall - draw similar to other DC fans of that class, 3A max, this isn't much. Permanent nature of fan is a byatch. I use 25-30 AH a day when I don't need fans and don't charge or run my laptop. With fans it jumps by another 20-30 AH.
Jonhm: with "shading potential" it looks like you're are close to making another full circle. You started with camping in shade, then added that there is usually some sunny spot 20-30ft away, so portable solar is doable, and now you are not sure again. IMO, the worst enemy of solar is rain, not the shade.
Edit - PS:
The answer to your question "solar or more batteries and better charger" is simple - get all 3.
4 battereis will get you through long weekend trip, you'll charge it when you get home. If you're staying in one place, you may bring 100W solar, batteries will be happier, but they won't die without it either.
For 2 weeks you need a bigger solar or generator - again, having both would be better.
For proper charging at home you will need to upgrade your converter no matter what. Or use 120V regulator like Meanwell.
