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.

yup when I was racing electric R/C cars if you had a good repoire with your hobby shop owner he would let you check the individual batteries you were buying from him so you could build a balanced battery pack and run cooler.
