You know that's a battery, not a "solar generator" or a "power station", so you're far ahead of many.
110W (maximum) of PV output isn't all that much, but it's something. The nice thing is the battery will also charge off of your truck and mains power. You can use a higher capacity panel, but you'd have to make sure it matches up with the battery box. I didn't check to see if the battery can be charged while in use, but it probably can. Doing that would let you run a fridge in your parked truck while off riding, with the panel charging it unattended.
LFP battery tech is good. It should charge/discharge quickly, with a lot of cycles. It's also a relatively safe battery type.
I'm not familiar with the brand. They've been around for awhile, but the move to LFP batteries is recent. Professor Hobo likes it. Go to 23:43 for his conclusions. There's some good information in the Amazon reviews and YT comments.
If you want a ready made system of that capacity, that seems like a good deal to me.
