When I get a chance to start using my truck camper more here is what I plan to do. I am going to put agm batteries in my duramax and and TC. Then I am going to get Priority starts on my Duramax batteries and use all three together. I know some will say this is not a good idea but I am going to try it out. I think it might just work fine.
Tried to make a clicky but didn't work. Check out "Priority Start" on
Amazon. Apparently lots of law enforcement and emergency vehicles use them.
Still curious if 11.7 volts will start a Chevy Duramax. Probably should as it will generally be warm weather.
JMHO
