When the livingroom slide on my 2002 Winnebago Adventurer (35U) is out, rain leaks in over the dinette.  I tried ordering a new seal from Winnebagoparts.com and they say that seal is no longer available.  Suggestions?

I have a 2002 Winnebago Adventurer and I want to use a ceiling tv mount for a 48" OLED tv.  I want to be sure I install the mount into the structural frame and I don't want to dril exploratory holes to find it as the ac plenum could be damaged.  I am skeptical a stud sensor will work with the sculpted carpet Winnebago put on the ceiling. I plan to install it just in front of the original overhead tube tv located over the engine cover between the two front seats.  Any advice on how to locate the "joist" in the ceiling to attach the mount?

Today, as I drove the unit back to storage, I was able to get an error code.  36.  Fuel pump and or Fuel Filter are the most likely causes.  I will order new replacement parts and see if that fixes it.  I will report back on success or failure.  Oh and the model is HGJAB.

If it were me, I would start with the most simple and least costly thing first, then work my way into more complicated possibilities. For instance, if you have a large fan that you could place to blow into the generator compartment from under it to increase air flow while sitting still, that would soon tell you if it is a problem of air movement and cost nothing. There are also several fairly good videos on YouTube that deal with testing and replacing the fuel pump and filter that you will probably find helpful. I watched 3 of them and while a bit amateur, they should help with your problem.

You mention that the RV is a 2002. Is it correct to assume that the air and fuel filters have been replaced as part of periodic maintenance? If not this would be a good time to change both of them. The other question that I have is whether or not you have checked for an error code? If it happens to be a code 36 it is quite likely to be a fuel problem. 

From the Onan manual:

 

Thanks for the error code description.  I probably have that in the generator manual somewhere.  I will see what the error code is today and post it.

I wonder if the problem might be that the generator is overheating when sitting still? Onans have an over temperature shutdown. I would look for something that might be restricting air flow when the RV is not moving. Where is the generator located in the RV?

If you remove that air movement restriction it will likely resolve the problem. 

The generator is on the driver side in the most aft compartment (at the rear).  Nothing has been modified or added to alter air flow.  I will locate the sensor for the over temp shutdown and see if I can replace that.

Yes, this is a gas  motorhome.  If the fan belt was off the water pump, the RV engine would be overheating and it is not.  That would be the larger issue if it were.  I suspect a problem with the fuel flow and the fuel line collapsing is a good thought.  I will check for that.  The line is original and so 17 years old.  Before the 200 mile trip to TN this past week, I filled the tank at the same gas station I've used for years, a QuickTrip.   I also added 3 bottles of STP gas treatment (75 gallon fuel tank) in hopes that would help.  It did not.  I'll get the error code today and check the air filter to the generator only because it's been awhile since I last checked it, not that I think it is part of the problem.  I'll also get the model number and research the fuel system design to check the fuel line and fuel pump and also the overheat sensor.

I have changed the oil and filter on the generator before this trip I took over 4th of July weekend.  I also had a full tank of fuel.  Basics, I've got covered.  One update, the generator now won't run for more than a few minutes even while driving.  The difference was the outside temperature.  The previous times I had driven it with this problem, were either overcast or early morning hours.  Today, while driving home the temperature was above 90 deg and the generator just wouldn't stay running.   I'll check for the fault code when I drive it tomorrow and see what it is giving me.

I think on the other RVing forum you pretty- well  were convinced to have the batteries load  tested by Interstate or another battery retailer.

You must have me confused with someone else.  I have not posted this issue on any other forum. 

All good suggestions and thanks.  The coach batteries are 5 years old but seem to be working properly, otherwise.  The air filter hasn't been changed in years so I'll check that too.  I am fairly sure this is a fuel starvation problem.  The problem occurs even with a full tank of gas.  I will research the generator's fuel pump system and call Onan for advice as well to see what they say.  If I decide to add a second fuel pump, how do I size it?  Where do I buy it and where do I install it? 

I have a 2002 Winnebago Adventurer I purchase new which has a 5.5KW Onan Generator (original).  It sat in storage for 18 months unused.  The generator started fine when I got it out of storage and will run as long as the RV engine is running and I'm driving.  If I stop, say at a rest area, shut the engine off and leave the generator running, it will stall anywhere from 5-15 minutes later.  I can usually restart it but it will stall more quickly, 1-5 minutes.  As soon as I start up the RV engine and get back on the road, I can start the generator and it will run until I stop again 2-3 hours later.  Within 5-15 minutes it will stall.  I've repeated this scenario enough times to know it is definitely related to when the RV is not running at high rpm.  I have tried leaving the engine idling but that doesn't seem to be enough, I actually have to be driving (higher rpm) for the generator to not stall.  I am thinking this is maybe a fuel system pressure problem?  Maybe a new gas cap?  I can't think of anything else and so I'm seeking help on this forum.  When it is running, it runs fine, no missing or sputtering.  It will sometimes sputter just as it is stalling but that is all.
