Default water tanks

Now that I've already ordered my tanks, I'm having second thoughts about grey and fresh water sizes. I am going to have 42 gallon black and 50 gallon grey and fresh. I spec'd these sizes based on some of the big pusher diesels. But now I'm having second thoughts.
I'm contemplating joining the fresh and grey and adding another 100 gallon fresh.
So my question is. How big are your tanks, and how do you use them. with my current MH we almost never dry camp, but when we do it's always a grey water tank that gets full to quickly.

Mine has 200 gallons fresh, 75 grey, 25 black. I bought it used so had no choice of sizes. I thought that black sounded kind of small. But, I've never come close to filling the black when the grey fills up. I am happy with these sizes. I think my wife and I can go about a week before needing to dump out. And that would be with taking several showers along the way because we jog and bike quite a bit. I like having 200 fresh. I like to fill those (there are 2 100 gallon fresh tanks under the bed) before we leave. I like to use my city water rather than trusting park water on the road. I never hook up to the park water when at a campground. I always like to use the water pump and my fresh water tanks for all household water needs. Much easier to turn off the electric pump when not needing it. I don't trust the plumbing system to not spring a leak and flood the camper with city water pressure. We also never drink the fresh water. Even though I do flush it out once a year and do the bleach treatment. I just buy gallon jugs of drinking water for $0.88 and we use those to drink, and make pasta.

We have 2 100 gal tanks under the bed too, but only 42 gray and black. When the gray fills up I fill up the black with it...... Takes almost two weeks to fill up the black, we can get 4 showers and daily use out of the gray tank, but sure wish it was bigger. Our trip out to Colorado was only 3 nights total in a campground, the rest of the time we use walmart or a parking lots. We are in Alabama and the rest stops have dump stations.... don't need them this trip but I have used them with my old class c. I also use a filter when I am at the camp grounds, not worried about the water. So I am happy with my set up except for the gray.

Ours are 2x 110g fresh (220 total) and 2x 55g black & gray (110 total).
220 gallons seems plenty for fresh (i sure as heck wouldn't want to run out of fresh water).

I (try to) only fill our fresh water tanks from known reliable sources (our house spigot). but we do use the park water when we have it (we just don't drink from it & we generally don't drink from our own tanks....always have bottled water). If were in a park (connected to city water), we turn the water supply off (via 1/4 turn hose/valve) when we leave the coach - just to avoid the chance of a flood from a busted water line or something) while were gone.

I filled the black tank once (occasional use while on my in-laws curb for 6 weeks) - i had a tank sensor wire break and didn't realize the tank was full...didnt have a problem but i would have taken action to drain it sooner.

I too wish the tanks were larger (but for the life of me as i think about it, i don't know why) - we've never filled the gray (or black) even on a long race weekend with several guys taking showers.

The gray tank is the least of our worries, if it gets (near) full, you can always just leach off the gray water into the soil (under the cover of darkness) - after all its just soapy...the trees and grass love it (and the soap can help to minimize bugs).

We're not full-timers & we don't stay in one place very long (unless its my MIL's).
we (mostly) use our coach like a station wagon, long road trips & occasional camping - we've never had a problem finding a dump station at some interstate rest area or camping world (free) & if necessary we could always pay to dump it at pilot/flying j truck stops.

our storage lot has a dump tank (and wash bay) - so we generally just bring home what we have and i dump & wash the tanks before i put it in our garage.

The old clandestine grey tank dumping process. I have to admit doing it also Never have had the black tank get full, but over a longer period the grey tanks get full.

if black water is in the gray water tank, could there be an odor/vent issue?

won't the odor / gasses in the (dirty) gray tank escape thru the sinks and shower drain? are the p-traps enough?

on a black holding tank it vents thru the roof and toilet is sealed with the valve & water to prevent gasses escaping into the living area.

heres an interesting configuration - EBAY Showhauler that has the following tank configuration...

150 Gallon Freshwater
72 Gallon Greywater for Rear Bath
72 Gallon Blackwater for Rear Bath
72 Gallon Greywater for Front Bath and Kitchen
72 Gallon Blackwater for Front Bath

the fresh seems a bit small for a bunkhouse.
I'd be more than happy with duel 72 gallon holding tanks.

Sorry for the confusion. I already have 2 50 gallon tanks. for grey and fresh. I'll put those in parallel and add a 100g tank for fresh water.

P-traps are more than enough to stop the odors. If they didn't you would have odors in your house since the black and grey water are in the same pipe and also the traps are the same ones in your RV.
