You'd think they could make the limitations human-understandable, wouldn't you?
I'm reading it as the maximum single tank size cannot exceed 60 lbs of actual propane capacity.
We have the same capacity single tank. Your total
propane capacity is
not 24.5 gallons. That is the WC or "water capacity" of the tank. Propane tanks are always specified as "water capacity" because the actual volume of a gallon of propane changes dramatically depending on its temperature but water does not.
Propane fills are limited to 80% so your (and our) actual propane capacity is only 19.6 gallons. Propane weighs 4.2 lbs per gallon so 82.32 lbs which, of course, exceeds 60 lbs in a "combination" of one tank.
Who the heck knows for sure? Not me. I'd call them to be certain:

The pic is of the data plate of our tank attached showing 24.5 gallon capacity (water capacity) in the lower left.
EDIT: I just used their form to send them this message:
We have a motorhome with a single propane tank of 24.5 gallons WC or 19.6 gallons of actual propane or 83 lbs of actual propane. The propane limitations seem to indicate we CANNOT use the CBBT.
I'm reading the "or any combination of cylinders less than 60 pounds LPG capacity" as limiting the size of any single tank of 60 lbs or more as being prohibited.
Would you please clarify that requirement?
Hopefully they reply.
At least for interstate bridges, the height specified on the sign is
not the height of the bridge. It's the maximum safe height for a vehicle passing underneath. The maximum safe vehicle height on US interstates is 13'6" without requiring a special permit. Semi trailers almost always are built to that 13' 6" spec to maximize their cargo capacity.
As an aside, that's why large fifth wheels often use a low-profile air conditioner in the front. A standard height air conditioner would cause the total vehicle height to exceed 13'6".
