Guess who's back!?! Atl-atl's K5 Blazer + Four Wheel Camper "The Crawlin Cabin" documentation thread!

Here we go. I started my search for a K5 Blazer with a Four Wheel Camper almost exactly five years ago when I first came across them and wound up with the FWC Hawk I had in my Dodge Ram 2500. Since then I have remodeled three campers, one in a very substantial way(Tacoma Fleet). A year ago I nearly bought a non-running K5 with a camper that was in shambles, Im glad I waited. Ill spare the details since this build will be posted across multiple forums and lots of people have already seen my previous work. If you are interested Ill include links at the end of this post.

It has patina, it has a little rust, it has a crapload of character and without further adieu, we have my newly acquired (4/9/2020) 1978 Chevrolet K5 Blazer + Four Wheel Camper Blazer.

Cheyenne trim level, 4x4, 5.7 auto. Arizona truck its whole life. Picked it up last Thursday, drove it home from Tucson with no issues other than a little float in the steering. Cleaned it up and tested all the systems Friday (everything works!). Managed to kill the battery because I forgot to turn the camper lights off when I went to bed. Woke up Saturday morning, finagled my Tacoma out of the garage to jump the Blazer that was blocking it in and promptly drove straight to the Tonto National Forest for a quick "test run" with a good friend who takes great pictures and makes great videos. He's talking about moving to Austin and selfishly I want him to stay in AZ and document this build in a much better way than I ever could.

Technically it has had "two owners" but in reality it is a one owner vehicle. It came with a plethora of paperwork including the original order card for the Blazer, the original order sheets for the camper and lots of maintenance records of years past. As far as I can tell its completely original and stock, except for maybe the wheels. They at least seem to be period correct.

At the moment Im researching until my brain explodes every night. This is really helping quarantine but not my pocket book. I unloaded the second of my two motorcycles today in anticipation of this truck taking up all my free time and disposable income. My plan last year was to go crazy with a modern camper renovation, LS swap, long leafs, 40s etc. but this one is so nice and so original I dont know if I can bring myself to do that, at least not to the camper... For now the plan is to fix up the interior of the cab for creature comforts on long drives. Make the stock drivetrain as bullet proof as possible for long drives and start building some axles outside of the truck while I learn the ins and outs of the K5 platform. I camp 25+ nights a year and plan to do even more in this rig.


Thanks for reading.

That is an awesome find! I am slowly working towards a similar set up with my k5. I can't wait to see more posts and pics for ideas.

All I have to say is congratulations on your purchase. It looks like time is reversed and we are back in the 70s with such a cool rig in great condition. I would keep the vehicle stock if I was you. It has far more character in its original form then it will ever have modified. I am looking forward to seeing your progress with this cool Blazer as well has the wicked adventures you get up to with your newly aquired truck. You must be happier than a pig in sheit with this Blazer. Cheers Chilli.?

Those wheels are 1990's vintage. Period correct would be 5 slot mags or one of the many varieties of "turbine" wheels for aluminum. Real deal Jackman wagon wheels in steel would also be period correct but they're getting hard to find...

Awesome, thanks for the info! I really want to run steel wheels but Im having a hard time finding what I want. Would it be weird to run 17s? I have some nearly new 315-70-17 BFG ATs that would be perfect on this truck.

My favorite steel wheel came on the military CUCV Blazers. It's a 15x8" that takes the factory dog dish hubcaps. I think Wheel Vintiques builds something similar. Another way to get that look is to take a standard set of 15x7 plain steelies and rehoop them with some 8" wide rallye wheel rims.

I have 17's on my Suburban. I like them and the tire selection but the "Soft 8" style isn't period correct. They are currently only available in black, the chrome is NLA.

The closest thing to a "period correct" 17" wheel is the American Racing "Outlaw II" style but I think they're only available in 8x6.5 bolt pattern. Maybe worth a look though...

Awesome find! Looks like it was used and loved just enough. I would be interested in a link to the build thread. I look forward to your progress. On the K5 FWC, does it open into the cab? Can't say I've ever seen one!

Here's a link to another K5 4 wheel camper build:


He has a thread on another site that details the rebuild of the camper but I don't have a link handy...

5 Slot mags, Vectors or Turbines. US Mag does make a 17" size of the slot mag wheel that would look ************** on it. I think the look of the slots would still feel period correct even in the larger size. Besides most of the younger crowd wouldn't pay attention to the fact that 17" wheels weren't available back then.

The 17's kinda look like 16.5's. I always thought 16.5x9.75 with a 33x16.5 tire were the perfect size for most rigs. The 17x9 with 33x12.50R17 is as close as you can get now days!

What is the current drivetrain? 350, TH350, NP203 with a part time kit?

My vote if you really plan to use it is to snag a 700R4 and NP208 or NP241 out of an 80's vintage truck. You can even make a TBI 350 look almost just like the original carbureted motor. The fuel injection and overdrive will really help with driveability.

IMO a NP203 with a part time kit is a ticking time bomb. There are several different kinds of kits to disable the differential in the transfer case. The cheap ones have blocks that replace the differential side gears. The better ones replace the entire assembly with a blank shaft. The common denominator with all of them is that once the kit is installed the tailshaft bearings only get oil when the box is IN 4WD!!!

Here's a good article that shows the difference in the kits that are available:


All that said, I really like the way the full time case works as designed. You may pay a small penalty in mileage but it's worth in in my opinion. If you feel that you need a part-time case, I'd recommend that you swap in a part time case, be it the 205, 208, 241 or whatever.

Also with the 203, a factory service manual to adjust the shift linkage properly will address a lot of the complaints with this case!

Lots of guys bad mouth the 208 but it's fine for 90% of people and has a much deeper low range than the 203 (2.61:1 vs 2:1). The 241 is a little bit stronger and has more aftermarket support as far as slip yoke eliminator kits and lower ratio planets. It has a 2:72:1 ratio I believe.

While you're working on the drivetrain, I would suggest upgrading to a 9.5" 14 bolt semi-floater rear end. This will give more strength and weight carrying capacity. A unit from a 88-98 (GMT400) truck is best. The "heavy-half" and light 3/4 ton axles are 6 lug. Make sure you get a unit that is from a 4x4 truck as the 2wd variant is narrower by several inches. This will also let you move up to a 1410 u-joint on your driveshaft. If you get a steel shaft from the donor it can be cut down inexpensively to fit your K5.

I would recommend upgrading the front shafts and u-joints as they are a weak spot with the added weight of the camper. Aftermarket shafts and the newest version of the u-joint (don't know the number off hand but they changed it again when the JK Wranglers came out) but it's much stronger than the originals.

As far as driver comfort, the biggest thing for me is that the wipers and washers on these trucks suck big time! Detroit Speed now makes a modern windshield wiper conversion that is sweet. You get IIRC 7 speeds and an electric washer pump. HUGE upgrade and pretty much looks stock except for the wiper motor under the hood.

I'm sure there's more but that's my take from daily driving and wheeling these trucks my whole life...

I honestly think that if Four Wheel Campers started make new campers for the old K5 Blazers, they would sell a ton of them.....even with the footnote that there may be sealing problems between the back of the Blazers cab and the camper. I know if they started them back in production, I'd be looking for a K5 Blazer right now. The size and platform would be an epic overland truck.

The K5 platform is just so easy to modify and pretty easy to work on compared to most modern SUV's.....I miss my K5.
