True deep cycle batteries like Trojan have no cranking rating. But my generator is started by my coach batteries. Would this damage true deep cycle batteries?

I am pretty sure all 12v Trojans have a cranking rating.
Either way, no it will not hurt a deep cycle to crank a generator.

The generator could be started from a motorcycle battery, the power drain is less than many people pi on their house inveter batteries
The Trojan will not be harmed by starting the generator
Options, always have options, and the journey goes much smoother

Our coach has room for four GC batteries T-105). That is it. They are both crank and house batteries. The starter for my 502 draws about as much as a 2500 watt inverter, but only for a second or two. It lights right off.

I've used a #27 deep cycle battery for 3 yrs. as a starting battery on my class B. I use it because it can be discharged deeper & more often than a reg. starting battery with out crapping out. I live in Minn. & while I don't drive much in the winter I do take it out once a month to work it out. It has NEVER failed to start. I'm sure your generator will pose no problem.

There is a secret cranking amp spec for a T-105. 500 CCA.

At 6V, I'm ASSuming.
12V should be the same. Seems pretty low to me for a pair of big batteries, deep cycle or no.

Yeah, me too, but I have been told that on two separate occasions by three informed people.

CCA is just a number derived from a test. Any battery can have a CCA if the test is performed.

Of course SMK is right. The CCA tests wouldn't normally be performed on golf cart batteries because they're not designed for that purpose.
I guess the 500 figure isn't too hard to believe. I think they could do more than that, but probably not for very long at all; I mean, like just a few seconds, maybe. Obviously I'm guessing here.
If the 500 figure is correct, then a pair of nice big T-105s actually might not be able to turn a 454 on a cold winter day. Kind of hard to imagine this since my single, little, Mega-Tron Plus Group 24 would barely bat an eye under these conditions, but again... different batteries built for different uses.
