RE: over heated & Broke down, Now in Prescott Az
I looked at a rig of that vintage that had a new Cummins engine at only 49,000 miles. The PO said there was a pin in the timing gear sprocket that broke, or let loose, grenading the engine. He indicated this was a known issue with these engines...?
Do a search for "killer dowel pin". Easy to "cure", can be expensive if it falls out.

RE: Electrical shock off of propane valve handle please help!!!
Turn off shore power and unplug. Still got the problem?
Have you checked CG outlet for polarity and ground? Is it a 30 or 50 amp outlet?

RE: A/C freezing up
Good information.
In order:
1. Verify that air return filter is clean and not obstructing air flow and that all outlets are open.
2. Run fan on higher speed and/or turn thermostat to a slightly higher setting.
3. If problem persists, verify that air plenum does not allow cold air to "recirculate" into the air return.
4. If problem persists, take it to a dealer-- it would be a warranty issue.

Are you plugged into shore power? Generator running?

RE: Exhaust Brake
Some chassis makers DO tie in brake lights with the exhaust brake, other do not. Good reason for either choice.

RE: Exhaust Brake
Roy....Some do, some don't. My 2005 Diplomat was suppose to, but somewhere the wiring connection is missing. I took it back to Monaco twice and they couldn't find what was wrong. It made me mad because I was trying to add the "Brake Switch" aftermarket accessory to mine which allows you to activate the exhaust brake by tapping the brake vs using the switch. It also lets you use the cruise control while the exhaust brake switch is on. The newer coaches do this automatically.CAT can do that, but it costs $200+ just for PC programming time. Grrrrr
The re-programming of the engine ECM charge for changing a Caterpillar engine to "LATCH" mode is up to the dealer. $200 sounds excessive and more than most have reported.
In LATCH mode, exhaust brake comes on when you are off the throttle and apply the service brake (even lightly). It then stays on (whether you stay on the service brake OR MORE IMPORTANTLY, TAKE YOU FOOT OFF THE SERVICE BRAKE until you apply throttle.
A very good choice, IMO. It allows for full time exhaust brake for any emergency stop, but also allows my favorite "gear" coasting!

RE: Houston, Tx to Eureka Springs, AR
You need to let us know your skill and comfort level in the mountains, as the direct route from Hot Springs to Eureka Springs IS reasonably narrow and winding (and beautiful).
We have driven it in our coach and enjoyed it. But at the CG we stayed in, the CG owner said if you don't now how to drive a big rig on grades you could damage your brakes (they said they occasionally smell rigs coming in with way overheated brakes. Don't think I used anything more than engine brake more than 2-3 times.

RE: Fluid leaking down inside front tire
The repair takes less than 2 hours.
BUT, I would not move it one inch until you verify that your oil level is correct. Any 90 weight gear lube can be used to top it off, as they will be draining and changing it when the do the seals and brakes. Have you popped off the center cap and checked oil level?

RE: Help!! Safari with a 7.2L Cat
A 1998 Cat 3126 is good for 8-9 MPG if driven conservatively. In the same coach, it will give you more power than the Cummins B engine and probably cost you a MPG or so. There are a lot of them on the road-- many medium duty trucks used the same motor. The 3126/Allison 3000 6 speed transmission it is mated with is an excellent drivetrain, as was your Cummins B if mated with the Allison 3000.
Yes, later engines with emissions controls got worse MPG.

Much of the answer depends on the driver's skill-- something we can't comment on.

RE: Fluid leaking down inside front tire
Front wheel will be gear lube from the oil bath wheel bearings.
DO NOT MOVE until you check the oil level-- remove the center cap. There is a clear plastic cap with an arrow and circle to designate the proper oil level.
There are only a few ounces of oil in there. Drive with no oil, and the bearings can seize-- not something you want to experience!
Any OTR truck shop can replace the seals-- and it takes a dial indicator to set bearing end play. Brake pads/shoes on both front wheels will need to be replaced.

RE: shocks
What year, chassis maker and shocks do you have?
How many miles on them?
Have you checked them-- are they leaking, bushings bad or not dampening properly after a bump?

RE: 22,000 to 23,000 lb rear axle
Dan,
Yes, the Federal bridge limit (used by many states and enforced by a few) is 20,000 on an axle.
But, I like to see a 22000 or 23000 axle as long as it is not loaded to over 20000.
That way the axle and components can be loaded to 20000 and still give you a reasonable safety reserve.
Said another way, capacity and actual weight aren't necessarily the same.

What chassis?
Advice for a Ford F53 won't do you much good if you have a Chevy P chassis.

RE: Solenoid testing
Lights work off the house battery bank, So, no light: showed dead.
The ignition/engine start works off the chassis battery bank: showed dead.
If you check voltage at each battery bank and it is 12.2+ (a 50% discharged battery as measured with the battery at rest) start by removing, cleaning and tightening the ground and positive wires at batteries and chassis, starter, etc.
