Are the Spec for Water/Grey Capacity Correct?

I'm looking at the brochure for 2008 32BA, and many other Allegros too and notice that the water tank is smaller than the grey 53 vs 70 and the black at 35. That's 105 gal of waist water but only 53 fresh. Are the specs correct or did they reverse the grey and fresh water?

Maybe that's an advantage, as I can haul extra water in some blue containers?

Now that I think about it, that is a good idea. Would not want to do the opposite and try and store waist water while boondocking.

I'm new to Class A ownership, but I've never seen an RV with a fresh water supply larger than the wastewater tank(s). It's too easy to overflow the waste tank if it is the other way around.

In our experience the grey tank is the limiting factor. 70 gal is enough space for a long weekend. I only have 50 gal waste water tanks with 80 gal of fresh. I can go almost two weeks on the black tank but we have trouble with the grey on a long weekend. I know there are lots of ways to conserve water but we do not like any of them.

A 32' Class A should have both black & grey at about 35-45gal holding capacity. Your fresh tank should be at about 50-60gal capacity.

I'm buying a 2008 35QBA. According to the specs (have not proven it out yet of course) I have the same size tanks:
Fresh - 53 gal
Grey - 70 gal
Black - 34 gal

I love the MH but the tank size bothers me as well. I would prefer more Fresh water since I have almost double the holding space as I have fresh water. For me it seems the Fresh and Grey are swapped as well. I could see using 70 gal of fresh water between the Grey and the black plus. But how will I ever come close to filling the Grey tank when boondocking? Plus with 3 boys I am worried about filling the black tank faster then filling the grey or running out of fresh water.

I do agree with you that extra water tanks might not be a bad thing assuming you don't go over your CCC.

Do like I do, carry a 5 gallon potable water container .....have on,y had to use it a few times. That's assuming you have a gravity feed to fill your tank...I think all Tiffins have one...

That's true for the combined capacity of black/gray vs fresh. But in most that I have looked at, the fresh is larger than either the black or gray but smaller than their combined capacity. So for instance a 2008 Voyage 32H is 78 fresh and 39/48 for black/gray. So you have 84 in waste to the 78 fresh. You could still over flow one or the other, so you have to be keeping track.

With the Allegro's you can't overfill that gray but you could the black. And the 2008 28DA it's 53 fresh to 35/40 waste which seems to be more like others on the market. Then when starting with the 30DA and up, the gray increases to 70 while the fresh and black remain the same. For those fresh capacity is about half of all waste. Seems like a waste of waste space

But as I said, I'm starting to think this is a good thing as I can carry added water as long as I remain within the CCC as mentioned by TooTallTom.
