Question:
We have two GPL-27T 12V 100AMP LifeTime batteries. Will this battery replace both we would only need one? Weve had these for 7 years and had no problems till we started seeing some issues with voltage being low when we are putting down or putting up our landing gear. And, is there a battery box that can be purchased to hold the new battery. We have a 2019 GD Solitude RES-R. Thanks so much for your time.

It sure will Frank. The Bright Way Deep Cycle RV Battery item # BRW64FR is going to replace both of your GPL-27T 12V 100AMP LifeTime batteries and give you a bit extra.
The Bright Way Deep Cycle RV Battery item # BRW64FR is a 250 amp hour battery. It's a 12v AGM battery that measures 20-1/2" long x 10-1/2" wide x 8-3/4" tall. It weighs 156.2 lbs.
For a battery box, I recommend the Commercial Grade Battery Box for Group 8D Batteries item # 329-HM484. This box measures 24-7/16" long x 15-7/16" wide x 12-5/16" tall and has internal dimensions of 21" long x 11-13/16" wide x 10-5/16" tall. It has a ventilated lid, 8 cable ports, and internal bumpers to prevent shifting and jolting.
If you have any additional questions, go ahead and click on the box that says Reply to Jerred H and I'll be happy to answer them.

Jerred, Thank you so much for the quick and informative response! I appreciate all of your assistance. Frank P.S. I'm debating upgrading to Lithium, but will need to change out our WFCO 9855 converter/charger.
