My only suggestion is to keep in mind that you will have approximately 500 pounds of batteries, so take care supporting that much weight. When you pick up batteries individually at 60 to 65 pounds each, it's easy to forget that together they weigh more than two generator sets, or the V8 engine in some motorhomes. Most cargo bays I've seen didn't look beefy enough to handle that much weight.
Regarding your wiring to make them identical, it's an excellent idea to do your best, but in the end not all your batteries will have the same exact internal resistance which is one reason many "experts" also recommend having fewer than 4 strings in parallel. This may become more of an issue as your batteries age, making them less balanced (notice most identical RV batteries don't fail at same time). Having too many strings in parallel also makes troubleshooting more difficult.
I really like what you're doing, and look forward to following your progress. I've looked at having the capacity of 8 batteries but haven't found a practical way to make it work for me. Please keep us informed.
