Want to upgrade alternator. Recommendation?

[jaywestfall]

I have a Mechman on my '04 Yukon XL 2500 and works very well.

Can't go wrong there!

Thanks for the recommendation. I am going to run this 145amp for a while and see if it is enough. See a big improvement so far. Right now I have the house battery out and that system all apart, waiting for Victron parts for the redesign.

Sorry, A little OT.
I have a 99 Express, 1500,5.7, High top. We use it for camping mostly but also works for a backup rig.
Alt from the factory is 145A.
I thought about adding a second battery but decided against it as i did not think that would last a weekend and it would be limited in what i could use electric wise and i was worried about a dead starting battery when time to leave. We always camp in remote places with no cell service and generally never see anyone else.
Have you considered 2 dedicated LiPO4 batteries?
I ended up installing 2 LiPO4 100AH batteries with all accessories ran off them.
I run a Renology 20A DC/DC charger that i can switch on/off when the engine is running to charge the accessory batteries. I also have a Renology 2000W inverter installed.
I can run a Keurig coffee maker, 19in TV for movies if it's raining, Outside LED lights at night, 12V fridge/freezer.(Nice to have Popsicles when it's 95 deg out) and interior light's.
For the wife and I this setup was a game changer for camping. It made it so easy and almost as comfortable as being home.
Going camping all we have to do is load up the fridge stop and fill up the tank and go.

Awesome setup! Love hearing how others have upgraded their vans for off-grid comfort. I’ve been debating a bigger alternator too for my 6.0 Express—leaning toward a 160A or 200A model. Also thinking of pairing it with a Norcold 12V fridge. Heard good things, especially for keeping food cold on longer trips.

WE just use a 12v fridge from Costco. Best purchase ever, you'll never go back to ice.

You don't have a Quadrasteer, do you?

I do not.

JS Alternators have some good options... if you're still looking. I have a 320 with a dual battery setup.
