Wildwood 251 SSXL

My question is having to do with my toy hauler it’s a 251SSXL. Wondering on the tank location, mine is laid out front tank is black, mid is grey and rear over the axles is fresh. My question is the front black tank has a small drain (2 -2 1/2inch maybe) where as the grey has the larger 3 or 4 inch drain. The unit does have a black tank flush system on it but the valves for the tanks are reversed as in the front small drain has a grey handle and the mid grey tank has a black handle, is this correct? I have verified the tanks by flushing the toilet and seeing which tank fills up. Wonder if anyone has ran into this.

Contacted FR via email and confirmed with Chris the drains are reversed. 1 1/2 is on the black tank and 3 inch on the grey. Will have to take it in for warranty. Disappointing will definitely screw up the Memorial Day holiday.
