We have 3 kids and if we're going to boondock every so often, I'd like to carry as much water (with commensurate grey capacity) as possible.The smallest high capacity unit I've seen is the Grand Design Momentum 328M which is 157 gal fresh, 104 grey, 52 black - but the unit is 36 ft long.

The law is probably different in Sunny California, but when I boondock, the gray water is not retained, except for the last day. The rest goes to water the bushes.I dunno what some folks put down their sink drains, as they will claim their gray water stinks. I've never had that issue, and I consider myself pretty sensitive to stink.Extra fresh water, a bladder or two in your bed should be no problem with the 5r over top of it, with that nice rig of yours, payload shouldn't be an issue. maybe two 60 gallon bladders on either side of the hitch?

Hi,You can add a 2nd fresh water tank to many RV's

pianotuna wrote:Hi,You can add a 2nd fresh water tank to many RV'sI realize that. You can also add water bladder in the pickup, Aquatank, barrels, etc. Then you have a tote that you can haul grey to the dump. But all that just adds more hassle.I'm hoping to keep it as simple as possible. If the trailer has bigger fresh and grey, that would be the best solution.

“The law is probably different in Sunny California, but when I boondock, the gray water is not retained, except for the last day.

Hopefully I won’t be the camper after you.

U.S. Forest Service says at https://www.fs.usda.gov/detail/mnf/news-events?cid=STELPRDB5066205“One critical thing people can do to minimize their impact on the environment is to properly dispose of both human waste and so called “gray water” from cooking and cleaning. Most people understand the concerns with proper disposal of human waste, but some are unaware of the problems that can occur with careless disposal of gray water. Used dishwashing water contains particles of food, which can create both a nuisance odor and attract flies and therefore disease. Soaps, even those designed specifically for camping, can have a negative effect on plants, soils, groundwater, and streams.L

That's a huge amount of fresh water for a small trailer. But it only carries 50 gal grey? Can that be augmented with another tank?

Yes 50gal grey and 50gal black. Doesnt look like room for anything larger.

+1 our 30ft toyhauler 5er holds 125 gallons of fresh water.

Personally I think the gray tanks, each if more than one, should be at least big enough to hold 75% of the gray water...unfortunately that's usually not the case. I have 110gal fresh and 82gal between 2 gray tanks, which always seem to be full way before I run out of fresh water.

I think I've posted this already but I have no intention of dumping my tanks at the camp site. If I need to dump, I'll haul the rv to the dump. That's another reason I'm considering the Grand Design Momentums - they have sizable grey tanks as well as the big fresh.

Most toyhaulers will have very large freshwater tanks, even the smaller ones can carry 100+ gallons. Just peruse the specs at various manufacturer websites, they all pretty much produce toy hauler rigs since they are so popular these days. Grand Design does make some very sharp looking toyhauler units, heard they have great customer service.

We prefer boondocking and with our 3 daughters, my wife, my son and I, we had no problem going several days without using the 110 gallons available on our less than 35' toyhauler. Finding a grey water tank that exactly matches huge FW tanks will be nearly impossible. Good luck, hope you find a rig that suits your needs and proves to be all you expected and more.

There are some nice 50+ gallon, food grade water tanks you can put in the back of your truck for around $150. It should be high enough back there that it will gravity feed into the trailers FW tank.
