  1. Yes, it is a Roadmaster chassis. Your system is using R134a refrigerant and requires a higher pressure to work well. R134a at its best does not work as well as R12, but it is what it is. I don't think your tech did a complete diagnosis to confirm what the problem is. It is most likely the expansion valve. If it not been serviced since 06, it needs to be replaced. Normal operating pressures are about, Low side around 50psi and around 350 to 450psi. If the compressor is making 500psi or more, the compressor is working just fine.  


  2. wolfe10, your wrong about a fully charged battery is the only way to be tested. A battery that is low will always test defective, but with a refracto meter,or a hydrometer(witch is not a very accurate tool), can tell you what the state of charge is in each cell. If they are AGM, Gell or lithium batteries you can use a DVOM to check the state of charge. Load testing a fully charged battery after charging MUST be tested twice. The first test is to remove a surface charge, the second is to test weather the battery can hold a charge.


  3. We tow a 2017 Ford Explore XLT on a tow dolly. Its a Tow Master with surge brakes. We have been using a dolly for many years and have had no problems entering any recreational facility.  We are not limited to any speed restrictions or time restraints. The only draw back is we need to be careful when pulling into a tight spot because backing up a dolly is a royal pain. We have about 6000 tow miles on the Ford and have not had any problems. Good luck with what ever decision you make. Remember "when momma's happy, daddy's happy".


  4. Sorry but I'm a very slow at typing. My first oil change was to a full synthetic oil (Delo). My engine temp dropped about 8*, but my performance also dropped. That's when I called Cummins and spoked to an oil engineer. I asked if he had any idea what happened, that's when he asked if I had just performed an oil change and if I did, was it to a synthetic. He explained what was happening, so I drained out all the Delo and replaced it with Valvoline Premium Blue and everything went back to the way it was.

    Some additional "technical info" on this topic.   This week I had my annual engine oil and filter changes performed by Cummins Coach Care in Houston while they had my motorhome for Onan generator repairs (I hit the twelve months since last oil change limit on my engine well before a mileage limit).  Since Cummins endorses Valvoline Premium Blue 15W-40 engine oil, Cummins Coach Care Houston only uses Valvoline for work they do.   I've never used a Valvoline oil in any of my vehicles before so during lunch today I perused the Valvoline website for technical details about the Valvoline Premium Blue 15W-40 engine oil.    Premium Blue oil is "conventional" meaning it's manufactured from crude oils.  The physical properties of the Premium Blue 15W-40 meets current API CK-4 and earlier specifications --> https://sharena21.springcm.com/Public/Document/18452/9c99aef7-c07e-e711-9c10-ac162d889bd3/ba8b3c4d-0abd-e711-9c12-ac162d889bd1

    The Valvoline oil replaces the Shell Rotella oil that was in my engine.  Both manufactures meet the CK-4 specifications.   What is the forum's experience with Valvoline Premium Blue 15W-40 engine oil?

    I only use Valvoline Premium Blue, that Cummins recommends. I had a lengthy conversation with a Valvoline engineer. He said that VPB oil is a blend, not straight conventional.I own a 2004 Holiday Rambler with a 330isc engine. When I did my first oil change, my fuel mileage dropped. Not trying to make this a long story but the combustion is also using the block temp to aid in combustion. I won't go back to any other oil brand.


  6. It's really not recommended to run two different tire sizes. the nose low looks might be just the way the body is hung. you can check frame heights with a tape measure to check if it's tires or body. you also might want to check your air bags. I would definitely would use what the manufacture recommends. Check with your local tire service writer and he can answer all your questions. 


  7. I just had mine repaired in  Chandler, Az. The problem is a very common issue. There is a magnetic switch in the door, I think it was in the left lower door. What happens is the door shims at the lower hinge needs to be replaced to allow the magnet to align with the switch. I fought with mine for about a year. There are other issues that need to be addressed. I would call for a Norcold auth. repair service and have the entire frig inspected. One of the issues is over heating of the cooling unit and in some cases, it turned into a fire hazard. Not trying to scare you, but get it check out by a professional.


  8. Depending on the time of day, you are going to be in heavy traffic starting in the Palm Springs area. I've lived in San Bernardino, Ca. since 1957 and the freeway congestion has gotten very bad. If you want to avoid heavy traffic, then you should jump up to I40 and travel west to Hwy. 58 in Barstow, Ca. That's where the 40 and I15 meet. Their will be a little traffic in Barstow, but nothing like I10. Take Hwy58 west to Hwy99 and go north. You can jump West on any highway and catch I5 north. Its a much nicer drive and no L.A. stress. Avoid I10 from Palm Springs at all costs.


  9. Herman, we are planning on being in Gillette, Wy., not with the grandkids. My son and daughter in law live in Oklahoma and are renewing their vows in June, so we are going to take a 2 1/2 month trip to the rally. Hope to see you again up there. 

     

     

     


  10. How ya'll doing. My wife [Paula] and I stated camping as a family in 1972. We started out on the ground in sleeping bags, but that got pretty old fast. Then we started using our pick-up truck with an mattress in the back. Later that year we added a camper shell. In 1980, or so, we purchased a Four Star slide in camper. We thpight we were in heaven. It had a ice box and a fresh water tank. It did not have any waste holding tanks and we had to plan all our travel stops were there was a Ice House, so we could keep the ice box cold. That lasted for a couple of years. We had three kids so we moved up to a 28' Fireball fifth wheel trailer and used it until I broke the frame supports in the king pin area. We traded it off on a 30' Fleetwood Terry Resort 5er but only kept it for a year or so. It leaked really bad when it rained and the dealer could not repair it, so we traded it for a 32' foot Snowbird. We used it until 2015 when we got our first class a motorhome. It's a 2004 Holiday Rambler Endever, 38' with two slides. We are in our late 60's and plan on traveling a whole lot more now that we are both retired. traveling with our grandkids has been a blast. I can't wait until our great grandkids get old enough to travel with us. Well we are getting ready to head out to the western area Indio Rally. Hope to see some old friends and make some new ones. See everyone on the road.

  11. If the backfiring only happens under a large load, like climbing a grade, and stops when he backs off the gas, its most likely fuel pressure related. (it's leaning out). If the backfires happening in the intake manifold, its low pressure/volume and if its happening in the exhaust, its most likely coil and/or plug wires. If all else fails, take it to the dealer. They are factory trained and have all the correct equipment to diagnose the issue. This is going to get real expensive if your just guessing what is wrong. Like I said in a previous post, I have 53 years experience in GM performance issues.


  12. Hey Herman, I resemble that remark. I'm sure Tim has a throttle body injection system. If he has had plug wire issues in the past, the first thing I would look at is the ignition coil. If you see any white stains around the ground bracket, the coil is breaking down due to being over worked ( too long at max voltage). Another thing to check is fuel pressure. The system is already a low pressure system to start with. Unfortunately you have to tee into the pressure feed line to get this info. I did have this problem on a customer truck and checked everything I just mentioned and it turned out to be a defective exhaust valve. The valve was starting to collapse. I am an OLD GM certified tech. of 53 years. You can PM me and I'll give you my phone number so we can talk.
