As we are searching for a new Class C, we are seeing some with 39-40gal gray and black tanks, and some with 29(ish) gal tanks. We are concerned with the smaller tanks as most state parks here in Indiana don't have full hook-ups, so we have to try to stretch it through the weekend on the waste tanks and dump at the end of the weekend. We can often get close enough to water for a refill, or they have water at the sites.

With our Outback 301BQ, we have 40 gal gray/black tanks and we have had to use the Thetford SmartTote to dump the gray during a weekend like this.

What do you all do with a Class C? Do you unhook and go dump during the weekend? Do you use the honey wagon and another vehicle?

Just thinking ahead if we get one of these units with the smaller tanks. Does anyone make an auxillary tank that works? Are there other options.

Thanks,

We have 30 gal tanks in our C... OK with the black for about 4 days (2 of us)
and the gray, if I conserve (like not running the water while rinsing the silverware, brushing the teeth and limit shower time) I can make it for the 4 days. However, normal usage on the gray is 2 days. Our last motorhome had the bathroom sink drain into the black tank and that was a nightmare! Every other day it had to be dumped, conserving or not. If I was really concerned I would get a tote or if at red light, unhook and go dump. I know, pain, but...

The secret is not to connect up to city water. By doing so we tend to run off less water and the tanks last longer.

I suspect that the RVs with the smaller tanks are made for folks like me that always stay at FHU parks. The smaller tanks wouldn't cramp my lifestyle.
But most folks buying their first RV don't know what they need, what's available or how they'll use it. More likely, the manufacturers are saving money and offering more storage space for things other than water and sewage.

40 gal grey and 40 gallon black and you are having to use a tote for grey to get thru a weekend

Need to do more in the conservation mode on use of water.

How many of 'you' are there?

x2 on "How Many?"

With 40-gal tanks, DW and I can go to nearly two weeks at the state park, connected to their water. We use the campground shower and use the outside shower after the beach. We don't use paper plates and wash dishes in the coach, with careful water use a the sink. Add Kids or Non-Campers, no way.

If we get to filling up our tanks, I think I'd rather get a cart than move the RV to the dump station. I've borrowed an 18-gallon one and that's enough weight to be walking it to the dump on pavement or packed gravel. Any bigger'd need to be towed with a vehicle.

I have 24 black and 60 gray in our trailer. We can easily go 4 to 6 days with three of us.
Does the camp have a shower house? Use it when convenient.

We can go five days with 5 people on 33 gallons of water and not need to dump the tanks.

If in a campground without hook-ups (most BC Provincial parks), we use the campground facilities most the time.

We use 'real' dishes.

We do not have a blue tote.

We can do 3 days with 4 people using our facilities and shower with our on board capacity.

Our bathroom sink drains into the Black tank. This is not an issue for us. We have never had a black tank clog or problem.

Our Motorhome has smaller gray and black water tanks. We can go 4 days before we have to dump. With our smaller motorhome it is quite easy to brake camp and go dump. Takes about 30 minutes. I think that 30 gal tanks are fine for two people. Perhaps not so good for a family of four or five.
