Holding tanks - sizes

We have a 2001 Jayco Eagle Class C motorhome. No where in manuals, doors in motorhome, etc. can I find the size of my black and grey holding tanks...The fresh water tank is listed at 36 gallons...

Not sure why you are asking? Would you like to know because of the weight? I guess you would like to know if your gray tank will hold a full fresh tank? It does make some difference to know how accurate are your needs. You can always do a rough calculation by looking underneath and meaure and multiply the height x width x length in inches divided by 240 will about equal the liquid gallons.

When the gray or black is full it will overflow and it really does not matter much how much Jayco says it should hold. :@
