Did you check the water in the chassis battery? The original batteries, both chassis and coach, in my 2016 Vegas are still doing fine, but I have been careful to keep the water up and never let them completely discharge.

Any auto parts place can match your battery for a like replacement. You can lift a top post battery with a pair of vise grips, or many of today's batteries have a built in strap.

I can't help you with the AGM question, someone else here will have to chime in.

You'll find a lot of useful information in the excellent crowd-sourced manual that forum guru Ed Felker put together. So superior to the generic manual provided by Thor.

I was able to spend a little time with the Vegas today and discovered that the Chassis battery has been replaced at some point with a Deka AGM. The date sticker is not punched so not sure when.
The reason I think it is weak is it reads 12.5 volts after letting it set for a day. The house batteries are always at 12.7 or 12.8 volts! Maybe I’m jumping the gun! Guess I’ll give it a little time and see what happens with it.

There was a printed copy of Ed Felkers manual in the coach! Yes, it is a awesome source of info and I have read most of it already!

Thanks for the reply Mr. Sun!
