2018 Tuscany 45MX house battery size?

For countless reasons I am replacing my 6 house batteries in my 2018 Tuscany 45MX. As some may know, all of the batteries are located beneath the carpeted floor, inside the wardrobe closet, and accessing them is not very convenient to say the least.

Thor tells me that they are GC1 batteries, but for the life of me I can't find that size ANYWHERE. Has any 2018 Tuscany 45MX owner every replaced their house batteries? And if so, what did you replace them with? What size did you use??

I want to put some AGM's in there so I don't have to check water levels on 6 batteries every month that are located inside the coach, under the wardrobe closet floor. The engineer's from Thor should have their heads examined! If you are going to put ALL of the batteries inside an extremely inconvenient location, at least provide batteries that DO NOT require any maintenance.

OK venting is all done.
Thanks in advance for any input and helpful comments.

Sorry can't help you but sure am glad that the Tuscany batteries are very conveniently located in an outside compartment on the drivers side

I changed to Trojan T105 AGM and couldn't be happier

They were a bit taller than the OEM flooded but exactly the same width and depth as the GC2
