Fuel is good 6 to 8 weeks max.
The only true hours on it is me running it once a month never really ran it more.than 30 minutes.
Was have only camped at site with plug ins no Gen needed. d trying to keep the kids cool in the back.
It wasn't until I tried To run the generator while driving because of the outside temperature an
Welcome to the forum, Builder-
You mentioned Onan failure while driving …… when needing additional AC for comfort in the coach. Over the years there have been many, many posts which echo your experience; many of those have been thought to be caused by vapor lock. Just a few comments on my ‘sperience…..so far. If you are getting the code 36 while troubleshooting a "cool" generator none of this rambling below would apply.
I bought my low-mileage coach used. From day one, the Onan would quit, under moderate load, if the ambient temp was 90 degrees or more. I installed the “scoop” from Jayco that channels/isolates the incoming cooling air ....... bringing it from the side of the coach, vice underneath + a metal vane assy from Cummins that diverts the heated air exiting the engine toward the rear of the coach. After those mods, I was able to run the Onan powering both AC’s (in the storage lot) at 95 degrees ambient air temp. Then last summer my daughter and grand daughter had the Onan quit whilst returning from Canada….at 100 degrees in Miles City, MT. (I was not along so I don’t know if the carb bowl was empty or not.)
During the off season I relocated the pump/filter and did a fair amount of insulating. We are now toward the end of a 7K-mile trip (mostly across cool Canada) and will be in Moab in about 10 days; the temp is supposed to be about 100 there, so I will have another data point. At some point along the way I will run the Onan with both the AC’s running (at 100 degrees, hopefully) and see if I am making any headway.
I plan to post a description of my mods with lots of pics later …... IF it shows improvement. For now I will attach a few overview pics that might be of interest. Probably have to click on them to enlarge for the annotation.
Good luck with the fix on yours. Lots of us folks are pretty ticked that we have to be “rowing alone” to have a generator that runs ……… when we need it most.
Best……………………… Ed S.
