Battery Replacement

[wiarcher]

I recently purchased a Redhawk SE 22C and I would like to replace the existing coach battery with two 100Ah batteries. I have explored the internet at length and it appears that the supplied battery is uniquely small and that any replacements that I can find would not fit. Has anyone else overcome this issue?
Thanks in advance

If they're Group 24 like mine, finding 100ah batteries will be tough. I was able to fit in two X2 batteries today. In parallel, at 76ah each, I'll have a total of 76ah at 50% discharge. Not planning on boondocking, but at least we can leave the rig alone for a few hours while we're at a park or museum, or whatnot, and the fridge will continue to run without low dc

You can possibly go to two 6 volt golf cart batteries, which are 210 amp/hr, but it will take remaking and rewelding the battery tray.

We have a 2018 29xk and with one limited space i ended up doing some modifications to battery tray and with reinstalling tray, slides, and battery as one i was able to squeeze in a single 12v Trojan t1275 battery and with 200 watt solar system battery stays charged, only run generator when running air conditioning, microwave, TV, etc.
