I'm building a system for my new RV using all Victron equipment, including a 24/3000/70-50 2x120 inverter, and I'm struggling to decide on batteries.
All of the equipment needs to go in my trailer's front pass through storage area (while still leaving as much room as possible for actual storage) so the size of the battery bank is definitely a factor. I'd like a minimum of 400Ah @ 24V, but higher is of course better as long as it fits.
I've used SOK batteries in my recent previous builds because I love the construction quality, but they only offer low Ah ratings in 24V and I really don't want to do series wiring of 12V batts.
Here's the batteries I'm currently looking at (along with some specs), but I'm definitely open to other options. I'd like to be somewhat cost-conscious, but reliability trumps cost as I need this thing to stay up and running even when I'm away and my wife is in the trailer alone.

That WattCycle is definitely the cheapest per Wh, and ends up with a significantly higher total capacity, but it's also by far the heaviest and largest setup, and I can't find much information out there about that model.
And here's a picture of the space I'm going to be installing in (from an RV dealer's site, as the trailer hasn't been delivered to me yet):
