sorry meant months. Unless your tanks are full all the time there is always a chance of condensation. All tanks will condense when not full--that's a fact of life. If your parked and moisture happens in the tank then how is the fuel water sep gonna get it all out? No fuel pickup line goes directly into the bottom of the tank. Yes bacteria grows at the moisture line. The problem I had in home heating tanks was this very issue. I'm just posting from experience. If y'all aren't having problems by all means keep doing what your doing. However the small price that a good treatment is far cheaper that me sitting along the road. And I'm sure putting one in to improve the cetane rating of the fuel. Once again only my opinion-- nothing more nothing else.

Buy fuel from a reputable source, buy and use quality water and sediment filters, and diesel fuel will last for years, at least the way we do it, it does.
Im with Ray.

Diesels Rv's "sit " better than gas rigs. Diesel is more stable by far.

Whatever issues diesel has - gasoline engines are far more finicky and prone to fuel issues. Ethanol makes gasoline far worse than it used to be just 5-7 years ago.

As long as one stays ups on the RV's maintenance all the items- batt condition, tire pressures etc the whole shebang- a diesel Rv thats excessed just a few times a year is fine. My own 98 with 24K miles on it could serve as firsthand evidence of class A's diesels longevity.

Given time all coaches compliment of appliances et all... will dry rot out from no use very little difference in that regard.

I can't for the life of me understand what the outlay for a diesel vs. a gas engine.....the cost of a oil change for a diesel vs a gas engine, the cost difference of diesel fuel vs gas.....on an on........I have a few years behind me, an I can never remember having any engine problems with a gas engine, never had an engine replaced.
My neighbor has a twin diesel with 682 TI engines, and from time to time he has to spend a lot of money to have his fuel filters changed, fuel run thru a filtering truck when he finds bacteria growth.

How come every engine discussion or question becomes a gas verses diesel argument? Both are good. Wy do diesel owners always bash gas?

IMOA the need to run a diesel more then a gas to own one. Is a myth.

I do add a stabilizer for the 7 month period. Same as I did with the previous gas MH.
Diesel has much better ride, quieter in drivers area, more torque in hills and better MPG.
I add nothing to mine, just fill as full as possible on the way home.

I'll give you time line from last year.
arrived home from Utah sept 2012 filled tanks full 15 miles from home (2) 50 gallon tanks. Parked vehicle and changed engine oil & filter
Drove to Harlan Ky March 2013 for the weekend Drove home toped off tanks as usual.
7-13 Drove to Mo on fuel in tanks. Drove home 2 weeks later.
Its now got fresh oil and the tanks are topped off again as usual.
Never even so much as a hiccup in my RV.

I will tell you the one fliud that doesn't like to sit and that is brake fluid.

As if you know what I paid for my diesel or gas rigs.

Why do people assume everyone with a diesel buys brand new list price rigs?

I'd expect marine diesels (or marine anything) to require extra maintenance over a road going vehicle.

Agreed on brake fluid - it absorbs water.

Some of my gasoline based device have less issues sitting-providing I fill up to the neck and I use Stabil.

Pickup truck
SUV
generators (2 honda 2K's and a yamaha genset)
My onan 4K won't run after a year of sitting and will need new carb (gum up)

Other gasoline devices I have care a lot about the fuels age- and can tell if the fuel is even 6 months old.

21ft speedboat with a high compression 406
30ft speedboat with a 700HP V10
Kawasaki KFX450
Mazda turbo sand rail.

Run year old pump gas and these devices notice the difference.
All these items require fresh fuel.
Im constantly draining and filling these items for storage.

Never ever had a problem with old diesel fuel as long as I performed normal filter maintenance.

Balderdash.

A 10 year old diesel won't always cost more than a new Triton based unit.

They only cost more if you let them cost more.
My RV is on a 1994 Ford truck chassis
with a 5.9L Cummins 6BT Deisel
I spend about $100 on a oil change using Rotella synthetic oil EACH YEAR.
My oil filter (napa Gold #1607?)is about $10 at NAPA
I didn't change the fuel filter/water separator last year or this year. (I did check it to make sure it had no water in it.) I believe the air filter was changed in 2011 I can't even remember how much it was ($33? sound right) .
I did change and flush the cooling system the first year I had it.
That is it all my maintenance for this vehicle.
They Can cost more but don't have to.

as bought for $2500


with the box installed (by me) new total $4000

If I understand what you're trying to say, you can't understand why anyone would ever buy a diesel pusher?

Many of us like the quiet ride and the way they handle. They also tend to do pretty well when towing and driving in the mountains.

Some will argue this point but not me.

I've never owned a gasser but I do know that DP's are expensive, but at least in my case, I feel the cost is worth it... to me.

OP:

Simply put, my DP only likes to hear one thing on the Radio: "Roll on Big Mamma" followed by "On the road again...." She misses her friends on the road at the Truck Stops of life.....

Many have much more experience than me, but as some have said - no coach likes to sit for months and months on end.

We do have a diesel polisher and additional filtering that I'm told is a waste of my money. Probably so on the technical side, BUT it makes me feel better so it's money well spend for my morale. :-)

I also drain a quart of fuel from my tanks when it has sat more than a month to make sure I get any water at the bottom before I crank it up. I also drain the filter and change my fuel filters FREQUENTLY. I'd tell you how often, but then many on this forum would proceed to tell me how I am wasting my money, etc..... As a piot and knowing the aviation maintenance rules, they seem to fit my DP as well. Well, not all of them. I have a hard time maintaining 250mph when pulling to most campgrounds, but my DW will tell you I try...

Filters are cheap compared to repairs. Ounce of prevention and all those sayings...

Best of luck on your decision. For me, it was DP or nothing.....

I believe the "branded days" are over, as I understand it now....
Actually no such thing as branded fuel. All gasoline, diesel #1 & 2, jet fuel, and several other petroleum products are piped to tank farms all over the US. You may be pumping shell gas or diesel into your tank from an Exxon affiliated or private refinery. The only thing that separates gasoline/diesel A from B are the additives like octane cetane boosters added to the tank truck as specified by the brand when loaded at the truck farm.
