I love this thing.
It made everything soo much easier.

I spent some time drilling some custom height holes for it.
I Figure I'll be adding a few more as this project comes together.
I also slightly modified the pads, the foam stuff they give you just splits and tears quickly.

The first thing I found was electrical tape, so I ended up wrapping it up with that...
I also extended the padding to prevent areas where I see it jabbing my grill and bumper in the future.

Planning to also pad the underside of the top of the creeper.
Where it sits above the truck, I noticed it's doing minor damage to the plastics with my fat ass on it.
Since I have a bunch of foam from the Cold Case radiator, I'll do the same tape + padding treatment with the red pad removed...

That ClampTite tool looks good as long as you have enough working space around the hose

I didn't want to bury my above question with the forthcoming wall of text. Last summer, towing the camper from Nashville to Denver, we spent the first night in Columbia, MO and as we were approaching downtown Kansas City steam came out of the vents and the dash went Christmas tree. Fortunately it was midmorning and I had an easy out from the center lane to a quick exit.

In limp mode, I get to the top of the exit, look right and see a C-store a block away. As I get closer, it was pretty busy and the pumps in the small parking lot were going to be a problem for pulling in the rig.

I look at the next block up and see an old fashioned fuel station with two bays open, the glass on two sides on a corner, and bathrooms around the side.

I pull in and see POLICE in big letters, but got in far enough to get the trailer off the street anyway. I park and hop out and see the steam cloud indicating to all what kind of trouble I was in, and was suddenly surrounded by helpful KC cops. I had pulled into an area KCPD fueling and oil change station.

One of the cops pointed out the heater hose broken at the connection while I was still closely examining the radiator. I called Good Sam road service, who promises to tow both your vehicle and trailer, and found that their approved shop was only 4 long blocks up the road I was on.

We waited an hour and a half for a tow that finally called and said it would be another hour or so, and the fueling station manager, who had come in after we parked in his lot asked where we needed to be towed. He said, "Unhook your camper and we'll tow you over", indicating to his worker to fire up the flatbed around back.

Got it to the shop and the owner told me he could cut and clamp or wait for GM parts truck to swing by in a few hours. You all know my answer!

So I currently have one ticking time bomb hose connector and one that's been cut and clamped, with camping season approaching, which is why I need a better than patched up repair.

The KC cops couldn't have been nicer and saved me from arriving at our next campsite after midnight. They didn't even give me much grief after seeing my trailer spare tire cover with a Denver Broncos logo.

Hopefully those cops at least said that the donkey is what made it break!

Good point.
Since I'll be using this against the firewall, it should be interesting.
With the engine out I doubt I'll have much of an issue.
But should i replace that hose later down the road...

Better plan ahead.

If they did I couldn't hear them through their Mahomes haircuts.

Per their online form:
Size "A" would be 5/8"
Size "B" would be 1/2"
Size "C" would be 3/4"

You can kinda see the numbers written on the ends in the pics in this post: https://www.tahoeyukonforum.com/threads/growing-up-doesnt-have-to-suck.93510/post-1451010

BTW, I'd advise you to NOT trim the two rear pipes as I did unless you have a bulb flaring tool. I didn't flare them and tried them as-is and, as expected, had a small leak. Either trim them for clearance and bulb flare them or bend them (careful to not kink 'em!) to get the end far enough away.

Honestly, you'd be just fine with new OEM connectors. This means NO Dorman or any other aftermarket brands! These should ease your mind if the plastic ones give you PTSD from your experience in Kansas.

Thanks. Great info. Being this is my first GM vehicle since I inherited my former father in law's '66 Bonneville hardtop 30 years ago there's still a lot of learning happening.

Man, nothing like having broken out your crazy high torque impact 1/2in impact that's dedicated to things that "don't want to come off"...
but still needing to use a 3/8in "impact" socket with built in swivel...
Used an "Impact" rated extension to get up in there, but it's also 3/8...
Broke out the face shield and gloves for that one...

Y to manifold is free!

Soaking the band clamp (that's near the muffler)
Silly bolt head is on top.
Not quite sure if I can get an impact up there without dropping the exhaust even further...

And I'm so glad my hoe was garaged most of its life.
So clean under there.
Amazed how clean the exhaust bolts are.


Staring at the bottom of this thing,
I still feel like I didn't miss anything obvious...
Just choose to overlook the many owners, with a few too many of them having it for such a short time.
Reminds me why i decided to buy this one.

Just some PO probably used cheap ass oil and still used the oil change monitor (and probably an extra thousand miles or two)...

Just cut that fu*ker off with an angle grinder. Band clamps are cheap.

Made it... Highway 36 made everyone car sick except muah and the downgrade coming into the coast heated up the brakes pretty good so I put the downgrade transmission assist to good use, helped a lot.
