I’m going to ask the collective one of those open-ended, subjective, maybe even cringeworthy questions:
What would be your top 5 mechanical updates/upgrades (besides the engine)?
My goal is to get my recently purchased GMC project as mechanically sound and dependable as possible, already planning on engine, transmission, radiator, etc). Thanks!
Rick

Mine came to me with several of the best upgrades, but I added a smart charger, 16" aluminum wheels, Six wheel disc brakes/reaction arm system, electric booster fuel pump. Jackknife sofa, 3-way fridge, and solar charging system. Hey, wait a minute, that's more than five (and I could name a few others as well).

Well folks,

I know I am going to be the old-man-out here and I really don't care, this group aka community is so friendly and understanding that anyone's position is acknowledged and respected.

So, here goes my big ones. (In order of installation only)

Pertonix replaced the points. (I see this as essential it is a mod I have a lot of experience around.)
Real CDI on the main engine. (This allows almost forever between tune-ups and platinum plugs last forever. She is a 73 remember.)
Progressive Dynamics converter. (After I killed the first house bank.)
Reaction arms on the rear drum brakes. (I think this is up there with canned beer.)

The next two are a serious dead heat....
A good radio and overhead speakers in the cab. (This one is now 16 years old and showing its age.)
A better cruise control with resume. (I think this is Mary's favorite.)

Both the cruise and the CDI are period correct (or close) they came out of my collection from past vehicles.

I do carry an original set of points in a jar because I am somewhat paranoid. The CDI box can be removed with the only change being that I would have to hammer the plugs back down to 0.035 or she will misfire.

And finally two honorable mentions:
The Pertronix trigger for the Onan points. (This made that otherwise reliable machine into almost a "forget about it".)
The Trimetric real battery monitor (That lets me always know the status of the house bank.)

Matt

top 5, would be ragusa step, LP fridge, roof A/C, dash A/C and macerator. I think every coach needs a modern converter and battery isolator valves, and a pusher electric fuel pump.


if you are asking about the stretch, I would be looking at some 3.7 gears, and I would just refurbish what you have for the rest. go through the bearings, brakes, fuel systems, and a set of airbags. you can always go to disk brakes at a later time once all other systems are in check.

should get that thing road worthy before sept, so you can take it to GMCMI.
