2018 Redhawk 29XK house battery replacement

Taking delivery of a preowned 29XK and here in Phoenix, 3 years is forever in battery life so I want to replace the single house battery.

I have researched till I am seeing double and figured I would ask all of you if there is a preferred Group 27 house battery that everyone likes?

I know they are typically a 1-2 year battery so my expectations are reasonable.

I do know it has to be deep cycle, size 27, etc.

I do have a solar system with lithium batteries as well but still want to have/use the house battery for APU starting, etc.

Your two cents is helpful and thank you!

I put an Optima $$ in my Jeep only to have it die prematurely. I put a Duracell branded Group 27 in the first RV and it lasted several years. So another Duracell "Marine/RV" G27 battery went in this RV only to have it die (but get revived) after 18 months.

There's an Intestate (Costco) up in the engine bay that's been alive and kicking for a long time. There's a couple of Walmart one's in the cars. They've lasted.

I dunno.
When it comes to SLA batteries, I'm gonna stay on the less-expensive side of things and not have a coronary if they go belly-up early.

I use nothing but Interstate battery in all my rigs

Have one in the RV Coach, probably put one in the Cab soon since it's almost 3 yrs old

I'm in AZ, so I'm an expert on crappy good ones
