Replacing 2 12 Volt batteries w 4 GC batteries?

We just (October) replaced the batteries and trays in our motorhome. We used the same size tray that had held the 4 group 24s that were in there. Here is a link to the Kwikee web site.

Part Number 9057090 will just hold 4 GCs. Note that 4 GSs will exceed the Kwikee tray load limit of 200 pounds. I check the tray every time I check the batteries and suspect that I may have to replace it eventually. So far it is standing up well.
