Is there an easy way to access the water lines without destroying the inside of the bathroom? I think the damage is caused from mice chewing a hole in the water line.

RV Doctor - How Do I Install a Replacement Powered Vent?
June 18, 2009 by Gary Bunzer · 5 Comments
Hello Gary, This is my first question for the RV Doctor. I just purchased a replacement powered vent for the bathroom of my rubber roofed Class A motorhome. I’m handy with tools and want to replace it myself. I know there is extra sealant applied around the existing exterior flange. The existing vent is a fan type also, so I won’t have to run power. I concerned about the sealant and I sure don’t want to damage the rubber roof while trying to get the old vent off. I know I need butyl putty tape and screws. Could you walk me through the procedure? - Richard Craig, (Middleburg, PA) Answer: Richard, when working with anything attached to the rubber roof, it’s paramount that the sealant you use be applicable and compatible with EPDM roofing. Any well-stocked RV supply store will have the correct sealant. I do recommend using Eternabond under the flanges of the new vent. But first, to remove the old vent, you’ll need to dig around each mounting screw to expose the head. Read more Tell a Friend Read More →
RV Doctor - Propane Furnace Won’t Light When Cold Outside
June 11, 2009 by Gary Bunzer · 2 Comments
Dear RV Doc, I have a 2001 Suburban propane furnace in my pop up camper that will not light when it is cold ( 45 degrees or less) outside. I have checked the battery and have sufficient power. The fan comes on but the ignitor never tries to ignite. When the outside temp is above 50, it will start right up. Also, once it starts once, it will re-start without fail as long as the unit is not allowed to cool. Could this be the sail switch or control board? Obviously the thermocouple works as it lights when warm. - Reed Meredith, (Mt. Crested Butte, CO) Read more Tell a Friend Read More →
RV Doctor - Is My LP Regulator Installed Correctly?
June 4, 2009 by Gary Bunzer · 2 Comments
Dear RV Doc, The first stage regulator diaphragm on my motorhome failed and was leaking LP gas out the vent hole. I had my service center replace it but I think they may have installed the wrong regulator. The work order listed the regulator as a 2-stage regulator VERT. I asked what the VERT meant and the tech said not to worry, that the regulator was installed correctly. Since he didn’t install a regulator cover I have some reason to suspect his competence. However, when I look up the regulator on the Marshall Brass Web site (the manufacturer) they show pictures of two regulator styles that are identical except for the vent discharge on the second stage regulator. I didn’t find enough information to allow me to decide which regulator model should have been installed. The motorhome has a horizontal tank and the regulator is also horizontal but on this new regulator the vent from the second stage regulator section is facing forward. I’m guessing that it should be pointed down. I’m trying to get information from other sources, but I’m feeling it may be difficult to get to anyone who knows about this issue. - Mike Rehmus, (Vallejo, CA) Read more Tell a Friend Read More →
RV Doctor - How do I clear my propane lines?
May 28, 2009 by Gary Bunzer · 4 Comments
Dear RV Doc, Recently while on a trip my hot water heater wouldn’t ignite. The technician at the dealer examined it and says there is oil in the propane lines and that I should break the line at the lowest point and at the heater and blow the oil out from the appliance towards the tanks. I am hesitant to open the line for fear of leaks in the future. Is there a better way to clear the lines? What can be done to prevent oil buildup in the future? - Russell Adams, (Mariposa, CA) Read more Tell a Friend Read More →
RV Doctor - Can I Modify My Fifth-Wheel?
April 26, 2009 by Gary Bunzer · 1 Comment
Dear Gary, I have a 2000 Fleetwood fifth wheel and I have to fit it into a very unique spot but can’t utilize my pop-outs because of the height. Someone told me that I can remove the tires, axle and leaf springs and set it down on blocks. I’m a single mom with no RV experience and am forced to trust stranger’s ideas. I found your site and would very much appreciate your time in providing me with the advantages and disadvantages of this idea. - Pamela Villa, (Northridge, CA) Read more Tell a Friend Read More →

RV Doctor - Atwood Oven Won’t Maintain Temperature
March 29, 2009 by Gary Bunzer · 4 Comments
Dear Doc, My problem is with my Atwood oven. It has never worked right from when I got the RV new. I took it back to the dealer and they made some adjustments, but it still doesn’t work. It is now four years old. The problem is the oven will not maintain the temperature. When it reaches its selected temperature the burner will shut off and never come back on. When I first light the pilot it takes about two to three minutes of holding a match under the pilot to light it. When the pilot does light the flame sputters for a couple of minutes then it seems to burn normal. I set the oven temp to 450-degrees or so and the oven will go up to about 350-degrees and then the burner goes out. Sometimes the pilot will go out also. My other appliances seem to work okay.
