expected normal voltage drop from load?
Is there a rule of thumb or guidance for an expected voltage drop based on amp load on a pair of 6V GC batteries? I was tinkering in my trailer this weekend and ran a 750 watt AC electric heater off ...

Ed, Next time you put a big load on those batteries like you stated above immediately go out to the batteries and feel all cables & connections, Be careful, something "might" be hot.
Quick & dirty way to check for bad connections or undersized cables. When I purchased the new to us Discovery I found a battery interconnect was hotter than a Chernobyl reactor core.
I purchased four Sam's Club golf cart batteries back in 05. The person I sold the prior rig to still using the same batteries! What I think the key here was I also replaced the converter to a Progressive Dynamics 60 amp smart charger with the charge wizard. I kept them watered, NEVER let them fall below 12VDC. First 8 years she was NOT plugged in during the New Hampshire winters. I'd fully charge the batteries and then hit the disconnects.
Treat them right and you will get years of service out of them.
