Hello,

We bought 2005 Holiday Rambler Endeavor 38 PDQ last aug.
We love it, but have few questions.
Appreciate any feedback

1)
Electric toilet. Every so often, it wont flush. I have read few posts, that say turn Chassis battery switch off or unplug fuse behind toilet.
These seem to work. But why do I have to do this?
Or does this mean, electric toilet needs replacing ?

2)
Can propane water heater be adjusted ?
Seems like when in shower, its too hot or too cold, cant find happy medium.

3)

We have the Cummins 400 hp engine.
Does that Economy mode switch on transmission, actually make difference on fuel mileage ?

If you don't have Owners Manual, you can download one from this link:

There is some discussion on the electric toilet. I'm not familiar with it but on residentials that I've worked on, the valves can get crudded from minerals in water.

#2. I don't think there is any adjustment, actually never even looked at that. The tank is only 10 gal, so quick showers or you run out of hot water. You can also use both electric and gas at the same time to speed up the heating.

#3. Mine has always been on economy, so I don't know how much difference there may be. But close to 9mpg on a 40' coach, I'm happy with that compared to many previous posts with a lot worse mileage.

I've fount that my electric toilet is very sensitive to battery voltage. If I'm plugged in and the batteries fully charged it works flawlessly. If I'm boondocking without shore power at some point the toilet will struggle to flush and even stay open. Haven't really done anything other then realize this could happen. There is a separate fuse behind/under the toilet, I've try the remove/install trick but it didn't help. I've removed my toilet several times over the last years and cleaned the seals and lubed the worm drive gear, this does help.

I would suggest finding an operating manual for your specific water heater, there may be an adjustable thermostat to control temp.

If I remember I put the transmission in Eco mode but I don't see much of a difference in mpg. Probably the best thing to do is slow down. If you find the rpm where the coach shifts into 6th gear and stays there.

When toilet issue has happened, we have been plugged in with full batteries. Batteries replaced few weeks ago.

Just wondered if meant electric toilet going bad. Turned off battery switch for awhile or unpligged fuse and let sit 10 min or so. And starts working again 🙃

We were having problems with our electric toilet as well on our new to us HR Imperial. After trying several different fixes finally bit the bullet and purchased a new flush mechanism from Amazon. Fairly easy to replace and solved the problems. Nice toilet when working properly. Good luck Don.

I have always avoided electric thrones from boating experience, they always seem to break at the worst times.
The water tank issue, I noticed too particularly after I replaced the electric element that didn't work. What came out (after I had to buy a real socket to get the thing out) was clearly the wrong part. The new working element seems to heat the water poorly, you get hot and cold - so what I think is missing is a mix valve. Current setup doesn't have that. So as suggested try using propane too, that is what I do and it works better. Yes it goes against being a cheapo when you get free power but whatever.

The answer IT DEPENDS.

Driving on flat ground (say I 10 across Louisiana) absolutely no difference. You are in 6th gear irrespective of power or economy mode.

Driving in rolling hills (say I 10 west of San Antonio in the hill country) it can make quite a lot if difference. In economy mode, you will be able to pull most hills in 6th gear.

Poster child for how to get the worse mileage in those rolling hills is in power mode with engine brake on. After you top one of those small hills, instead of coasting and building a little speed for the next hill, you are braking and then as you start up the next hill going immediately from braking to wide open throttle. Can you drive that way-- sure. But, don't complain about MPG or the jerking back and forth as you choose to make the transmission repeatedly down/upshift.

The decision to use economy vs power mode is absolutely a personal decision. I have always driven with MPG in mind. I am in economy mode 90% of the time. I use the down arrow if I need a lower gear then either up arrow or "D" when you want the higher gear. But, if passing on a two lane road (where I am willing to sacrifice MPG for speed) I am in power mode.
