Is anyone using a group 27 agm in their Tin boat? Currently, I have the regular old interstate 27 the dealer installed in my RT188, but it's going dead. I was told Deka offers a 27 agm, but I am looking for other options too?

27's will be fine for trolling batteries for most people. My opinion you need a bigger battery for the cranking battery. Your engine, trim, pumps, electronics, lights all run from the crank battery and very few people run the engine enough to keep it charged up.
I understand, I've had 31's before. I've also see the amount of work you had to do to get them in your RT. I'm going on 3 years with the current 27 and I've never had a problems, fishing sunrise to sunset, fishing tournaments, running 2 HDS w/ structure scan and point 1, and the livewell. Don't see any reason to switch, if I haven't had any problems with these. It's just adding more weight.
I got 4 years out of my Group 27's, replaced them with the same but I did make sure that I got the Group 27 with the highest cranking amps that I could find for the starting battery. There is quite a bit of variation in Group 27's and some of them might not be sufficient. I though about going with AGM's but couldn't find them when I needed one.

Do you have a Sam's Club around you? If so, go in there and get their Marine AGMs. They are made by Duracell. The manufacture of the batteries are all the same for the most part. I have 2 group 31s. They are amazing. Never ran out of battery, ever.
