You would have to consult Spartan. In more recent years, a single filter was usually installed on the pressure (engine side) of the lift pump. If a Cummins engine, go to this Cummins website and enter your engine serial number: https://quickserve.cummins.com/info/index.html Here, for example is our 2003 Cummins ISL fuel flow diagram showing the location of a single fuel filter between the lift pump and CAPS pump: https://qsol2.cummins.com/qs3/portal/service/manual/en/4021418/ NOTE: if these sites do not open (they are for my engine serial number and my personal Cummins QuickServe account) you will have to go in and set up a log in (it is free and VERY helpful).

At that age, the likelihood of failure is much higher than with new tires. Not sure you want a statistical analysis-- they just need to be replaced.

Many of us have the external TPMS on our toad in addition to the standard one provided by the vehicle manufacturer. NO PROBLEM.

6 VDC deep cycle batteries are widely available. Walmart, Sams, Cosco, etc all carry them. Interstate and others have good specs on their websites. As far as upgrading, much of that depends on the room you have to install them.

Yes, the 2% change with every 10 degrees F is a pretty good approximation. Anyone who wants more accurate info (can't imagine why), the Ideal Gas Law from your high school physics applies: PV=nRT.

Remember, the tire pressure rating (really the minimum PSI for the maximum load) is ONLY with the tires at ambient temperature before driving. The tire manufacturers know that driving, exposure to sun, etc will raise the temperature. Not a problem.

In a word, NO you can not cover the outside vents. Air circulation behind the refrigerator is critical to the cooling process. But, sealing the sides so that the outside air does not get into the coach should have been done at the factory and IS something that you should do.

Yes, Yokohama is certainly one of the options.

At 8-9 years old, it is time to replacement them-- period. Even with excellent care they are at the end of their useful life. And, if not kept out of UV light, properly inflated 100% of the time, etc.... well they may be way beyond their useful life. And, sorry, never heard of Yamaha tires. Check again on the brand recommended-- there are a number of good choices.

Marvin, Welcome to the FMCA Forum. What is the age of the tires on the coach now? The last 4 digits molded into one sidewall of each tire indicate the WEEK and YEAR of production. So 2401 would have been made the 24th week of 2001.

Code 329 MAY indicate a problem with a component, but very first recommendation is to clean all the connections to the CAPS pump with a good electrical cleaner such as DeOxit. A poor connection can easily throw a 329 code. These connections are easiest to access from ABOVE (bedroom floor, bed or closet floor raised).

readysetgo, Welcome to the FMCA Forum. One of the more important attributes of a good tire cover is that it not only keeps UV light off the tire, but also keeps it COOLER. So, if you use "on the tire" covers white tire covers are better for the tire than darker ones.

Carl, Since the metal could have come from either your engine's fuel system OR a stations, my advice is that as long as you have no performance issues, change the filters and see if you continue to get metal. If so, the presumption would be it is coming from your engine's fuel system. Does the electric fuel lift pump sound normal (have someone turn the key to the start position, but not start the engine while you are by the passenger's side rear of the coach). You should hear the electric lift pump for 1+ minutes?

Many tire manufacturers make the 265/75R22.5. You can also look at Michelin 255/80R22.5 XZE or XRV through the FMCA Michelin Advantage Program. The 255/80 if virtually identical to other manufacturer's 265/75.

Since this is 50 amp (at least, that is what we can ASSUME, as the OP said they have a 50 amp coach) reverse polarity is all but impossible. Yes, if plugged into a 30 amp outlet with adapter, reverse polarity could be a lot more likely issue. Said another way, reversing ONE hot and one neutral can happen. Reversing TWO hots and a neutral-- can't see that happening.

Ramble2Gether, Welcome to the FMCA Forum. By law there will be a GVWR plaque with the OE tire size and recommended PSI (the PSI based on each axle being loaded to GAWR (Gross Axle Weight Rating). This plaque is normally located near the driver's seat, often outboard on the wall. It will also list the OE wheel size. Please post both OE tire size and wheel size and we can help with good, current choices.

But hard to calibrate for applying specific torque. Can be done, but not a precise.

Thanks for the update. Sounds like we may be back to "start by replacing that one outlet". But, are you sure that the converter is on the same breaker/circuit as all the other outlets??? Most coaches have a separate breaker/wiring for the converter.

Be aware that the Cummins system is designed to work under a slight VACUUM (i.e. to suck fuel from tank to pump). I am not aware of any data from Cummins on the effect of supplying positive pressure where the system was designed to work under slight vacuum. Absolutely agree-- too much restriction can certainly cause issues-- whether in tank fuel pickup, hose length and/or diameter, hose routing, restriction in primary fuel filter and/or secondary fuel filter. From Cummins document 018-016: Fuel System For CAPS Fuel System: Maximum fuel inlet restriction at rated HP measured at lift pump inlet: 4" HG. Maximum fuel inlet restriction at rated HP measured at CAPS pump inlet: 10" HG.

I agree, Both excellent suggestions. McDonald Observatory to confirm their Star Party info: https://mcdonaldobservatory.org/visitors/programs/star-parties

Again: Agree, pedestals/shore power can be defective. But, it would affect far more 120 VAC-powered items than just a converter. Is this the ONLY circuit that is not operating properly?

krischampy, Welcome to the FMCA Forum. With 120 VAC confirmed to the outlet and the converter working when plugged into another source, the first thing I would do is replace the outlet. It may be just corroded enough or loose enough that your converter plug is not making good contact. An inexpensive place to start.

Ya, the only reliable answer would have to come from Freightliner, Gaffney. If there was a history of large chunks clogging primary fuel filters, that MAY justify a 104 micron pre-filter.
