I was concerned about the mild colored frothy discharge after my first winterizing but I too musta got lucky after my first (mild) winter. I'll not take that chance in winter #2. Maybe your post will make more sense after crawling underneath, but I don't understand what the Valtera cap screws on to. Is there a fitting that goes into the new rubber T that you installed, and this cap goes on that fitting? All of this stuff goes immediately upstream of the macerator - correct? Thanks

Great mod G! Thanks for sharing. This one is going on my to-do list.

The Valtera cap (or the sewer hose) screws into a coupler such as the one described here:

Amazon.com: Valterra T1029-1 Termination Adapter with 3" Bayonet x 3" Spigot: Automotive

This adapter is connected to the Flex-T with a clamp.

I forgot that part. Sorry for the confusion. And yes, it all goes upstream from the macerator. Basically, you are removing the following:

3" to 3" coupler
3" to 3" hose adapter
3" hose

and taking the 3" to 3" hose adapter and tossing the rest, and then it goes:

3" ABS pipe from the valve to the 3" Flex-T (inserted over the end of the 3" ABS pipe).

The saved 3" to 3" hose adapter then goes on the other end of the Flex-T with the smaller end for the 3" hose with a clamp, and then a short piece of 3" hose connects to the macerator with a clamp.

You put the Valterra T1029-1 Termination Adapter with 3" Bayonet x 3" Spigot on the other opening of the Flex-T and the cap on that.

It's easy to see once you take a look under the van. The only thing not easy to see is the 3" to 3" hose adapter. It's clamped on to a 3" coupler that is then connected to the 3" ABS pipe on the other so the flexible hose can be connected to the macerator at the factory. Since you are using the Flex-T in the place of the hose, this adapter has to go on the other side so you can connect the 3" hose to the macerator.

Hope that helps.

It's the age-old problem of erosion beneath the concrete surface because they never bothered to install proper drainage. Water works its way down through the slab joints, scours out the underlying soil, and then the weight of the vehicles crushes the overlying mass. The rebar usually remains in quite good shape as it ends up in a tangled bird's nest at the bottom of the hole. Good rebar structural integrity has a lot to do with why it is so effective at ripping tires clean off rims.

Well,

Installed the new Hellwig sway bar. Ride is exceptionally improved.

But protag you were correct. It is up against rear of generator. Not sure how much and if there is movement against it.

I will be keeping a close eye on it.

My husband notes that this is only an issue on the newer Interstate models, if anyone was wondering. There is no potential interference imposed by the upgraded sway bar on the generator in the case of our T1N-based Interstate.

I do agree with the phrase "exceptionally improved". My only regret is not knowing about this issue sooner.

I drove it again today on I-95.

Nite and Day.

Why did I wait a year? Why doesn't Airstream do this mod?

One may never know.....

While I can understand how a sway bar improves handling, not sure how it can improve ride quality.

Why doesn't Airstream do this mod? When I asked my husband this same question yesterday, he started uttering expletives. I think the short answer is that Airstream doesn't do many of the things that it arguably should do in the name of basic business integrity. In creating the Interstate, Airstream fundamentally changed the dynamics of the Sprinter, but it opted not to make the corresponding stability modifications called for by its own design. And the rest is history, which involves a lot of unnecessary stress in driving, at least until one discovers the mod that should have been done to start with.

I figured you, if anyone here, would know the difference.

The sway bar can have a negative effect on ride tho since it couples what one side does to the other. On a rig this size I'm guessing that would be minimal when compared to a small car.

With the heavier sway bar, Koni shocks (ala Sprinter Store), Sumo springs spacers front and rear; my 9 foot tall Sprinter drives more like a sports car. It tracks and corners very well and wind does not make it feel like an uncontrollable slab. All the difference in the world of handling safety.
