So what did you do to your GMC today?

Also made some cribbing pyramids for the front end.

Yep, those would be a lot simpler and easier. I think I might have just enough material left over to make a set. Thanks for the inspiration. 🫡

Okay, Larry, done!

Can't believe I never saw front ramps posted before or IRL - obviously a better way to get the front up quickly and easily. 🤷🏻‍♂️
 
Nice looking!! One more thing, Put a 4X4 block across the back edge so you don't accidentally drive off the back. Same with your rear ramps. Don't ask why I suggest this. But, nice job.

I had a SOB before the GMC, I had a 4x4 on the ground as a stop when backing in.
The SOB would hit that like a brick wall.
The GMC? I couldn't even feel it, drove right over it

-Cleaned lithium grease out of 4 drums.
-Clean and inspect all bearing (they were good).
-Repack bearings with proper grease, new seals (.025 proud as the safety wire I had was that size so we just go with it!)
-Install 4 new KYB rear shocks

This morning I'm marveling that this thread, started 1.25 years ago, has reached over 500 posts! That's probably a record -- congratulations @RvRev2! Maybe someday I'll query the database and generate some additional stats about it.

In the end it's just a small-talk-around-the-campfire social thread. Nothing earth-shattering, just a chronicle of the comings and goings of our TZE brethren and sistern 😉. Unlike most other threads, the content is freeform, meandering intentionally. Like Seinfeld, it's a show about nothing. But, we get to see something priceless, that is, a record of what owning a GMC Motorhome is really like. The ups, downs, and in-betweens.

The best part, though, is the consistent good-natured tone of these posts, no moderation required. What a treasure in the online social media world where manufactured outrage is the soup du jour! It recharges my house batteries which have been stressed of late given the global state of affairs. I'm deeply grateful.

Today, for me, marks the beginning of preparations for camping season 2026. This will be my 8th year of GMC Motorhome ownership. I'll be removing my front wheels to start the process of changing the tires from Michelin Defender LTX M/S to Michelin Agilis CrossClimate 2. I was planning to try the Cooper HT3's but the Michelins were only about $20 more (each) and they're severe snow service rated. I'll also be switching from wheel weights to Counteract balancing beads. Finally, I'll change the oil along with the oil cooler adapter seal which has been leaking. I found the correct part (Dorman 917-036) which should seal better than the oil filter gasket that's in there currently.

The to-do list is pretty long this year, including an unusually large number of issues that arose during our trip to Florida over the holidays. Thankfully none of them involved a mechanical breakdown. I'll also be converting the coach to lithium house batteries this season. I was already planning to do this, but as luck would have it I won a giveaway from the RVing Today TV show sponsored by Go Power / Dometic! The package includes a smart 100ah battery, a 3000W smart inverter/charger, a battery monitor, a 130W portable solar panel, and a wiring kit. All I need to add is a DC-to-DC charger to charge the house battery from the alternator. I'm thinking I'll use a combo unit from Renogy that includes a solar charge controller.

Thanks again, friends, for making this community so special!

Other than being offended by the SOB in the background, nice setup! 😉
Actually they upgraded me to some of their newest gear:

ADV-LIFEPO4-100 100Ah Advanced Lithium Battery (incl heater)
AIC-3000-DL 3000W Advanced Inverter Charger (split phase for 50A service)
DC-KIT-5 Install Kit
GP-PSK-130 Portable solar kit (might not use this for the coach as I already have a portable Renogy panel)
GP-BMG Battery Manager Kit

Bled the drum brakes but ran into a bunch of issues in doing so. The good news was I did manage to get new fluid all the way down both sides at the rear
The bad news: I think one of the rubber lines is collapsed on the passenger rear as only a very small amount of fluid would come through (vacuum bleed) on the passenger rear drum. I even took the hard line off of the cylinder and same result.
Passenger forward drum bleeder is seized (even with vise grips as a hail mary!). Took hard line off of it and was able to vacuum out a lot of fluid.

Since its looking like I will have to replace the rubber hose T, I tested removing the hard line at the T and the fitting is already rounding off, so its seized pretty good. Will probably need to vise grip it to get it off. I've got everything sprayed with penetrating oil. Do you think its worth hitting it with a little heat? I know we cant get things too hot because of the fluid.

I guess if I'm replacing the rear hoses, I may as well just do all of the cylinders so that everything is new. I cant wait to get to the front! :ROFLMAO:
 
I haven't posted since my intro post and air bag incident however..... Been getting after it on the Kingsley and over the winter I've replaced the Exhaust System, Serviced the transmission that didn't appear to need anything, Removed a substantial amount of non-working radio shack junk from out the dash and under the hoods, Removed the 16.5's and placed new wheels and tires on there and am now looking into getting the Onan more reliable.

Not all today but a start!
 
Installed Microlevel system. A little head-scratching, but overall a straight-forward setup. :) Apparently at some point I will need a Viair or similar compressor upgrade as the Firestone compressor is a bit under-powered.

Those rear wheel cylinders are so inexpensive, just replace with new. And put a larger one on the middle axle, they are from a similar year 1 ton chevy truck. There are a few choices, choose based on bore size.
