Steve,
My OEM configuration was for 7 group 31 batteries, so I'll be going down in weight and up in capacity.
In a truck Camper? LOL.. in a Motorhome they are set up for large banks. in a 5th wheel when you have lots of pin weight and the empty front gen compartment it doesn't matter how much you have, but I find with my truck camper I am looking to maximize the power to weight to size ratios. it was very unfortunate that last summer shipping was three times what it is now, but when I put the new power centre, solar system and such in I did make sure they were all LFP compatable so when they did get afordable the switch would be easy. I also bought the cheepest lead acid deep cycles I could.
as for under the bed, not where I would look at installing them, but if you look at the configureation of my 5th wheel the battery compartment is under the bed. if I upgrade that one to LFP they would be under the bathroom instead in unused space in the heated basment. but if Sio2 started to come down in price they would probable deserve more consideration, but I can see paying twice the money for the same AH when for me the -40C/F camping isn't a thing.
