I'm just thinking out loud here but maybe instead of the single G31 for the trailer I should buy two G24 AGMs, put one in the trailer as planned & the second in the truck, and invest in this new CTEK 12 volt charger to maintain this truck auxiliary battery.

Do NOT replace the flooded lead acid battery in your truck with an AGM battery ! Your trucks charging system will NOT properly charge it, leading to a short life.

Where did I say anything about replacing the truck starting battery? :h

My apologies.
No worries, I re-read my post yet again to make sure I was clear in how I thought I could take advantage of this new CTEK DC charger, and I think I was. :) Over the winter I've been considering upgrading from my current CTEK Multi US 7002 7 amp charger to a CTEK 25000 Multi US 25 amp charger featuring temp compensated charging that would be more suitable for maintaining a costly AGM battery. However, now that you've brought this new CTEK DC charger to our attention I'm thinking this may be a better option, even if it means removing the battery from the trailer to the truck those few times each season I may need to recharge it before we get home. It's a conundrum - I really don't need the reserve capacity of dual G24a on a regular basis, yet that space GM provided in my Silverado for an auxiliary battery isn't big enough for a G31 ... arrghhh. :M I'm going to have to take another look to see if there isn't some way I could squeeze a G31 in there ... if so, I'd buy this new DC charger instead of the 120 vac CTEK 25000 so I could recharge the G31 while driving. Anyway, thanks for the heads up on this new charger. :)
