#A for me with both of my toy haulers.
A couple of questions for you:
1. Do you dry camp?
If yes, then you'll need a generator.
2. Do you run your AC much?
Again, you'll need a gen.
Having said that, if you're starting scratch and trying to economize, you could apply those same funds to a good solar system, four batteries, and a portable gen.
Since we added solar, we rarely run our gen. We run it for about 20 minutes before bedtime if we've been sloppy with our power usage during the day. We also run it any time we're using the air conditioners.
Happy shopping!
