1996 Carri-Lite 528RK holding tank sizes

[Ramseyjack]

Currently in Tucson at Voyager (Thousand Trails) RV park so not an issue.

I have the factory documentation that came with the 528, and not a single spec on any tank size.

I found out the fresh water tank size by measuring the gallons in after sanitizing the fresh water system (30-gallon tank)

So the RV industry would call this a 36-gallon (6 gallon hot water tank)

The gray and black tanks used to read useless data (lights) but now nothing but green (bottom light)even when off grid for 5 days.

Been using RV Digest-it and seems to have made it worse.

Does anyone know the waste tank sizes for the 1996 528RK?

I can fill them and overflow them when I get home, but not here.

Thanks

Jack
