Both 65's and 31's fit under the seat (I have 65's in mine) but I hear the 31's just barely make it from another member on here but I'm sure you can't use the factory hold down with either that's why I was curious if you could with the 24's.
If I was willing to spend the money I'd personally put 2 8D batteries in my Humvee but it would require more work as you would only be able to fit one under each seat and have to run more cables between them. Still cheaper than 6TL's tho and probably 1000 more CCA and double the reserve capacity not that you would need that much.
