Awesome. Did you figure out how to get your interior lights working in your trailer? and a trailer battery charger? Theres a wire roled up to the right of the fuse box under the brake cylinder.

I'm gonna play devils advocate, but if I had a choice between a normal 75 amp alternator, a 125 amp alt, and twin 125s, I would take the 125 amp alt...easier and cheaper to fix when it kicks the bucket.

Have you thought about replacement costs?

Nice truck too :)

This truck has complete coverage bumper to bumper parts and labor for 5 years or 100000 miles! The only parts not covered are belts,bulbs,wiper blades and filters.

There are lots of GM kits to add that to any Duramax. It's nice if you need lots of light! I just wish that they also had an option for battery combiners like larger boats. Then you could still start off 2 batteries, but only drain one from accessories, yet still automaticaly charge both.

My trucks are used in my business, parts do need to be replaced from time to time, as they do wear out. Repairs are a normal business expense. When the time comes to replace an alternator, i buy a new one, no big deal?

Ford Alternators are way more versatile and way more fun.

a single 125 amp alt. would not be fun in the winter while plowing. i know my 140 amp had trouble and finally kicked the bucket after 5 winters of use.

True. I'm a small business kind of guy...I look long term. One big alternator would be better for me than 2 larger alternators.

Athough if your chevy lasts past 5 years... :laugh:

I don't do snow plowing or have knowledge about it...never occured to me that you'd need a large alt for that purpose.

Yep, the hydro's on the plow suck out a lot of juice as well as the lights, heater, a/c, radio, strobes. They'll kill your batteries if you don't have a good alternator. The plows work faster with dual alts because they give out more power and recharge the batteries quicker.

You will love that truck. I have a 2006 LBZ 1ton SRW crew cab 4x4 LB Duramax/Ally. I have 58,000 trouble free miles so far.:cool2:

Thanks for the schooling, I've never done snow plowing or plan on it (FL? Snow? Are you kidding? ) so that thought never occured to me.

Yep. The guys who bought 2001s worked out most of the bugs with the DM/Ally, 8.1/Ally combos.
