RE: Brake Issue
Could be a defective relay valve not releasing or operating slowly. ??
Maybe a kinked air hose. ??
With MH stopped, press hard on brake peddle then release and listen for the air to exhaust. Is it instant or time release?
I've worked on hundreds of air brakes on semi's but got out of it before disc came out so I'm guessing a lot.
It should have standard generic air brake parts available at large truck parts stores.

RE: Difficulty timing a 1995 Chevy 454ci
Here is one kit that I found on google- https://www.summitracing.com/parts/smp-pr131t?seid=srese1&gclid=CjwKCAiAu5agBhBzEiwAdiR5tCYx3zV6Y93elFiMk0_QcCX3LwfZN_A5TmNh2G_6kDkYmG0ieaNZEBoC0xgQAvD_BwE
I had a 1989 Chevy PU and replaced the tbi regulator back in about 1995 and it was a common problem back then.

RE: Difficulty timing a 1995 Chevy 454ci
Running rough, backfiring, TBI's are known for having pressure regulator in them get weak.
They are cheap and easy to change.

RE: GMC Class A
I see them for sale on FB Marketplace here in Florida often.
Usually in poor condition or salvage.
I have wondered what kind of gas mileage the get?
I have had 2 Winnebago's 1974 and 1983 and lived with 6-8 mpg and wondered how they compare?

RE: 1991 P30 454 intermittent surging, power loss
I don't think it has been mentioned but, next time it is warmed up and acting up try removing the gas cap and listen for a vacuum sound.
That would point to an emissions problem not venting.
Another wild shot, possible muffler partially blocked.
If it was a Ford you would be spending money on suspension corrections.

The Throttle body has a fuel pressure regulator in it and they are known to get weak over time.
They are inexpensive and not too hard to replace.

RE: Hot Exhaust On Differential
Maybe the CO will get you before you get home while you are saving time!
A Co-worker died from a damaged exhaust pipe on a generator on a rental MH with only 2500 miles on it.

RE: catalytic converter stolen
So why don't converters have VIN numbers on them like so many body parts?
