I am in the area but without the MH. I plan to be at Gerhart's after noon Friday to help if needed.

Larry, In addition I am thinking you might be getting air in the fuel system. Check your fittings and lines on the upstream (suction) side of the transfer pump. A fuel gauge on the supply side is a good tool.

A few of my favorites... Maint1 - I hope my drool will wipe off the 3408.

Here ya go Gregg...

Weather forecast is showing rain showers Turdsday thru Saturday. Unless the forecast changes I will not be bringing the MH but will be there to support the show/club.

I don't do tabaco, will plain spit work? I am using the red and blue nylon seals with the stainless steel screen insert. The supply (red) seems to be loose. I will try tightening the clamp. I do not have an air dryer. Truck was not spec'd with one. I have a check valve at the wet tank inlet with the SS line from the compressor connected to it. The wet tank leaked down within a couple hours before the valve was installed and it STILL leaks down. The LH tank has a check valve at the inlet port and the line from the wet tank is connected to the valve. I am not loosing air in the secondary or LH tanks overnight. MOF, the pressure after two (2) days was about 70psi.

Never thought about the cab air bags. But that does not explain why the wet tank leaks down within a few hours (even with a newly installed check valve). Can anyone recommend good quality gladhand seals? Or are they all the same. I been using white lithium grease on the seals.

Well the air leak saga continues. On Wednesday afternoon I installed a check valve at the inlet of the wet tank. Thursday morning before I left for Winchester, NO AIR IN WET TANK! It leaked down overnight even with the check valve. I pumped up the air and did a quick soapy water check but did not see any bubbles. Driving to Winchester, the air compressor cycled every 10 minutes. So I concluded I STILL have an air leak with the trailer connected. Today (Saturday) before I departed Winchester, I pumped up the air and did a more thorough check with soapy water. No bubbles at the check valve tank connection but saw some bubbles at the trailer air supply gladhand. I did not hear any air leaks at the back of the trailer (brakes or air bags). I checked the gladhand seal and reattached the gladhand making sure it was snug. On the return trip to the farm, the air did not leak down as rapidly. I estimate at least 30 minutes between cycles. Need to try different gladhand seals but still puzzled why the wet tank leaks down even with a check valve. Stay tuned...

Back at the farm. Great show. Over 300 vehicles. Weather was warm on Thursday and Friday but cooler today (Saturday). Saw other dog, Underdog, maint1, and mhfred. BTW, I "roughed" it two (2) nights. Slept on the sleeper mattress in the trailer. Best sleep I had in months!

Ron, You had me worried (not about the eating part) but they were closing. I just called and they are still open for business. As for the all you can eat stuffit buffit....Les helped too. And I remember seeing a blue mini-Mack sitting in the parking lot!

You lookin' for Amish gals dressed in kilts? No Kilt but lots of good food...Lititz Family Cupboard, Hershey Farm, Oregon Dairy, and Good 'n Plenty to name a few. Don't forget the Clam Bake on Friday night at Gerhart's, you will not go away hungry. Vinny, How many times have we told you...stay away from wimmin!

Doug, Cancel the order for rain this year!

I remember a story about this MH or another RHD MH from a Mack ED&TC engineer. When they drove the truck on the highways around Allentown, people would do a double take when seeing the passenger on the left side sitting with their feet up on the dash.

Yea, hot air!

Drove the MH (bobtail) to Hagerstown, MD to participate in Power Day. From Breezywood to Hagerstown (about 55 miles/1 hour) the air pressure never dropped from 130psi. So life for the MH is good! BTW, Power Day was great. Thursday will be a run to Winchester with the trailer.

Success at last!! I installed a check valve (Bendix 800376) at the LH tank inlet. The air pressure this morning (both primary and secondary needles) is 80psi, down from 125psi. I calculated the air leakage and it is about 3psi per hour. Saturday will be my "check" on the running air leakage (compressor cycling) during my bouncy trip (without trailer) to Hagerstown, MD.

My favorite bus is the GM Greyhound Scenicruiser. Second favorite is the Crown bus especially the tandem axle buses. And why didn't Mrs. FWD "doll up" for the Nunnery?

October in PA = possibility of sleet, ssssnow, and salt.

Excellent show and venue. Too bad it was so stinkin' hot but at least the A/C in the museum was working. Kudos to Doug and the Museum staff for their efforts. Always something "new" to see at the Museum.

Affirmative...I plan to arrive around noon on Thursday and depart Saturday afternoon. Going to "rough it" and sleep in the trailer both nights. Not sure if Capt. Barry will be there. You all missed a great Trucktoberfest on Saturday. But it was HOT!

If you license it as an "antique", most states restrict the usage (i.e. parades, shows, etc.) but cannot be used "for hire" or commercial service. Check with your state BMV to be sure.

Sean, I did a full brake application for about five (5) minutes (my leg was getting tired) and the needles never moved.

I think I found the cause of my air leaks. First there is to be a check valve in the line from the RH primary tank to the LH tank (at the LH tank). I cannot see one, unless it is an internal check valve in the line. That might resolve my "parked" leak down. Now for the big one, my moving leak (hopefully) is at the trailer gladhand port on the trailer. I replaced the gladhand seals but there is still a major air leak behind the clamping mechanism (don't know the correct nomenclature). Is there a gasket/o-ring between the stamped steel bracket and casting? If so is it replaceable? Or is the glandhand seal the "gasket"? I searched the Great Dane parts catalog and Sloan but I do not see anything concerning a gasket/seal. Anyone know what I am talking about? Or do I need to replace the complete "port" on the trailer? See attached pic, do I need to loosen two (2) torx screws and reposition the gladhand seal? UPDATE: Being the inquisitive engineer I could not sit back and do nothing. So I removed the torx screws and the hex bolt (at the top of the picture). This allowed movement of the red bracket but not able to remove (round head rivet at the bottom of the bracket). But I could see behind the bracket and there is no gasket. I removed the gladhand seal, cleaned the casting and seal, used white lithium grease, and reinstalled the seal and screws/bolt...NO LEAK. So now comes the road test on Friday. Stay tuned for the continuing saga of "Roll Hauler Express Air Leaks". BTW, I checked the tractor brake cans and there are no leaks. In all the "excitement" I forgot to check the trailer. I will do that on Thursday.
