Biggest truck camper not for f450 550

Probably talking about the F450's. Since what, 2013? or so Ford took off the 19.5 wheels and reduced the payload capacity of the F450's so that the diesel version of the F350 could haul slightly more weight (depending on trim) and the gas F350 were rated substantially higher in payload.

I believe for 2015 you can now order the old F450 as a F350 (under some sort of some sort of package ncluding the short turning radius) as well as the original version of the F450 with the 19.5 wheels and greater payload.
