The Alliance brand is reasonably priced even at the Freightliner dealer. BTW an 8 gauge charge line is ideal. Use a good size double break relay and be sure to control it so the relay is not closed while cranking the engine. Otherwise that line will see some starter current. Consider some type of over current protection. You have power on both sides. I like fusible links. Cheap and easy.

Dennis,
And I still can't type on this Windows 8 Phone!

Very helpful Dennis.

At $125.96 Cnd. for a group 27, I have to wonder if it's the same
battery as the Alliance you write of.

Easy enough to find out.

Of course I misplaced the notes I made, but IIRC, the warranty on the
Alliance up here is 1 year against defects then pro rated for several
years after that.

I apologize to all for the charging wire gauge question. I received a
pmail regarding that info and I bet there's more info on that in the
archives, seeing as how this battery stuff has been discussed many
times.

Neil.
