Trackers aren't worth it anymore.
I go along with the gang.
When I built my racks I had the crazy idea of building trackers, never again, and I have some pretty sophisticated equipment here from electronics to machining. Bottom line, I wound up making the racks stationary and adding a couple of panels. lighter, less to go wrong and cheaper. My last modules cost me less than a buck a watt.
I think, if you can afford them, the Lipo batts will save you weight and space. I'm moving away from L/A batts now. After ten years of using them in my system (eight Rolls 530S's) I'm ready for less maintenance and a battery to simply take up the slack when the grid fails. The rest of the time I'm happy to feed the grid and have a negative electric bill.
One more thing, if I was doing an RV I'd look into flexible modules, there's something about dragging along rigid modules while going 70 mph that makes me uncomfortable!
