Yup, that Monty has that much! You are referring to the gray tanks and the capacity is divided between the 2 gray tanks (lavatory/shower and a separate galley tank) with 46.5 gallons for each tank. You also have a 50 gallon black tank, and a 66 gallon fresh water tank. It sounds like you are gaining over 50% capacity of the galley tank from your prior rig.
I got this info from this link:

Don't forget to consider this weight when calculating the GVWR when the tanks are filled and you need to tow your rig somewhere carrying all that weight (hopefully to a dump station close by or dumped at the campground). If they are all full you'd be adding about 1,740 lbs just in fluids if all tanks are full (209 gallons times the 8.33, the weight of one gallon of water). If you've used up all the fresh water and just the gray and black tanks are full then the weight drops to about 1,200 lbs (143 gallons).
My TV wouldn't be able to carry all that weight driving on the open road with the extra weight on the pin since I can only carry about 500 lbs. Likewise my Monty only has about 500 lbs before it's overweight on its axles. So I dump at the hookup or call for the honey wagon. Hopefully you have a beefier truck than I do and the trailer has plenty of margin in your 3,248 lbs of cargo weight. My Monty only has 2,000lbs of cargo weight to spare and I already carry about 1,500 lbs of junk in the trailer as it is, leaving only 500 lbs on the Monty.
