Morebeer 1550 - Using bigger kettles?

I'm about to buy a used 1550 tippy system with the 15 gallon kettles and want to know if I can use the morebeer 26 gallon pots on this set up. The information on the morebeer site seems to indicate that I can, but I've also read some posts online that say the 1550 frame is too small, and I'd have to get the 2050 frame.

Anyone have a definitive answer? How about using larger kettles on the 1550 that aren't manufactured by morebeer? Anyone have luck with this?

Morebeer's site says you can go 26 gallon.

As long as it is the new style of 1550, you can use the 26 gallon kettles. You will have to buy or build the mash tun basket for the larger kettle. The older style of 1550, you cannot use the 26 gallon kettles without major fabrication.
