Black tank

We have a 2017 Jayco 27.5RLTS and according to Jayco it has a 32.5 gallon black tank. We do a lot of camping that has water and electric but no septic. Has anyone or anyone know if a bigger black tank can be put in the 27.5 ? Or maybe a second tank installed ? Thanks for any help

Black water is not usually the issue. Most people can easily go 5 day on a tank that size. Grey water on the other hand, people have issues with filling very quickly. Many places state it is against their policies to dump the grey water onto the ground.

Personally, I have not heard of anyone putting in a larger tank. Generally speaking it is not a pleasant job. With an enclosed underbelly, it is a huge undertaking, and new brackets will need to be made.

There are a lot of different tank sizes and configurations. I would take a look on Amazon to get a base idea of tank options.

Personally, I would invest in a good quality portable waste tank with good wheels (maybe a wheel upgrade) that you can pull behind your TV.

You can also use a portable macerator pump to fill/empty the tank

I agree with the portable waste tank and macerator idea. I have the macerator (to use at home because I have a LONG way to my clean out), but no portable waste tank.

I considered getting a portable tank for a while. Not so much for black water, but grey water could be a problem every now and again. I ended up abandoning the idea because with judicious management, we can get a week out of our tanks, and we NEVER go that long without some kind of dump facility. If I know I'm going to have a grey water problem, I can carry a 5 gallon water tote (found it washed up on the Padre Island National Seashore) to "dispose" of grey water. It's not terribly efficient, but it'll work in a pinch.

The nice thing about the macerator and the tote tank is that you can put the tank in the back of the truck (or on a "stinger") and pump the waste into it. This opens up far more options for where to dump it since you can either pump it back out with the macerator, or use some "stinky slinky" and dump using gravity. And you can haul it as far as you need to to find a suitable waste facility as opposed to towing it behind the truck.
