I just got this old Coleman. It's really cool and pulls well behind my Vanagon but needs a lot of rehabilitation before I can take it camping. I just posted an intro thread here.

It's cool that it's so old that the roof is just a metal frame with a single layer of aluminum, so there's nothing to rot up there.

The first order of business is to make it less of a hassle to use.
1. The door hatch was a pain to use -- you had to wiggle the key just right for it to turn and then if you twisted the handle all the way open, the lock bar would get stuck inside the door until you teased it back out because it was just a little too short. I took the hatch apart and replaced the slightly-too-short lock bar with a piece of scrap steel I had in my garage. I also pulled all the tumblers out of the lock cylinder so it turns with a screw driver -- I figure if someone wants to break into my trailer bad enough to jab a screwdriver into the keyhole, it would probably be in my best interest to minimize damage. After pop-riveting it back together it works great. YAY!

2. The top was REALLY hard to crank up -- Like the top crank wouldn't move around at all, and I could only raise the top using the bottom crank, pulling hard enough to drag the trailer tongue around, and that couldn't be right. I checked the cables (all OK) and gave the wiffletree some much-needed grease, but it was still really hard to crank. I figured it might be the bearing so I took it apart again to disassemble it and realized this pin (#8) was sheared off:
VveJ4wT.jpg

So as I cranked up the top, the threaded rod wasn't held back by the collar (#5) or spinning the bearing (#6) and the threaded rod (#10) was just pressing into the frame crossmember at the rear with the whole weight of the top. I removed the bearing, dug out the solidified 1960s grease, cleaned it in lacquer thinner, repacked it, and replaced the split pin with a new one from the hardware store. Once it was all back together, it cranks up pretty easily with the faster upper crank (which I couldn't even turn before). YAY!

I kind of like how this camper is built to be totally torn down with the "1960s guy tool kit" (pliers, adjustable wrench, hammer, drill, punch, and pop rivet tool).

I also pulled off half the canvas, washed it, and attempted some repairs...the canvas doesn't look so bad in the pics, but the string holding it together is turning to dust and it has some significant rips. When I'd attempt to sew them up, the canvas wanted to rip where I placed the threads (and sewing it with my home sewing machine was way harder than any other upholstery project I've tackled before). I'll probably end up ordering a new canvas.

Next steps:
  1. Tape over the seams on the top and repaint it.
  2. Fix the broken wheels on the bed slides (which cause them to sag and drag over the stored dinette cushions, ripping the upholstery)
  3. Paint the body
  4. Replace the cracked old wiring to the tail lights to make them actually bright enough to do anytihng
  5. Order, receive, and install new canvas
  6. Clean the inside and prime everything with Killz, followed by new paint
  7. Reupholster the dinette cushions
  8. Build a new swing away kitchen
  9. New tires
  10. Maybe a new Dexter Torsion Axle with electric brakes
  11. Add a 20mm ammo can tongue box
  12. Solar panel, battery, interior lights, and a diesel heater
  13. Add a Port-a-potty
I'm hoping to get at least 1-7 done by mid-April so I can use the camper as a basecamp for a backpacking trip I'm planning in Utah, but time will tell! I'll try to keep this thread updated with my progress!

I suggest replacing the rear lights with LED ones, and replace the clearance lights with LED's. They will be brighter, cause less problems and will work all the time. On my '93 Coleman I was always having to fool with the bulb in the clearance lights to get them to work, so replaced them with LED's and no problem since. LED's inside will reduce the drain on your battery.

I had that set trailer for many years and it served well. Yours is nicer, mine was $50 completely stripped (just a square space with a roof that went up and down). I put the heaviest trailer tires that fit, and used it for hauling and camping with plywood sides I'd pop in place. I have to say it towed great loaded or empty.

These oldies are super rare, nice find and good luck with the rehab. Just in case you are looking at canvas, Bear Creek Canvas did right by us and our 86 Coleman Columbia.

Thanks for the heads up! LED bulbs are on my shopping list!

It seems like it didn’t come with a battery or any 12V things in the interior. The only electrical is a 110V outlet that goes to a hook up cord on the tongue.

My plan is to get a battery, solar panel, and controller and wire up USB ports on the inside to charge phones and run LED string lights…but that’s still a few major projects down the road!

I’ve been working on the roof of my camper…since it just has an outer skin with nothing inside to get wet and rot, it doesn’t have to be perfectly sealed…but my roof needed some attention.

The roof panels are riveted together through a D-profile vinyl channel that was seriously degraded and cracking, with multiple layers of cracking dirty caulk on either side:

So I cut off the brittle outer curved portion of the vinyl and used my heat gun and scraper to clean off most of the old caulk

Then I re-caulked any remaining cracked sections with Amazing Goop Marine Sealant which dries to a clear, hard, flexible, paintable surface. When that fully cured, I covered the rivet strips in 2” Eternanond tape

The roof sheets are aluminum, but the corner caps are steel…and were rusty

So I treated the corners with Corroseal I had left over from another project…Corroseal is really awesome — it looks like milk or thinned Elmer’s glue, isn’t stinky, cleans up easily with water, and converts rust to an inert black oxide that is paintable and doesn’t rust further

After treating the corners and seeing all the rust turn black, I caulked them up with Amazing Goop

Finally, everything had dried/cured tonight so I threw down a coat of gloss white Rustoleum paint with a roller. What a difference!!

I still have a few spots to touch up, but I needed less than a quart of paint. I also ended up using less than a tube of Amazing Goop to do all the seams, corners, and the angle around the perimeter.

Thanks…Those guys seem awesome…I called them a few weeks ago and they were super nice answering my questions about the thread they use and why…they seem like a high quality outfit.

I fixed the saggy bed slider that was rubbing on/wearing the dinette cushions!

I pulled out the slider. One of the 2 plastic rollers was broken clean in two with half missing, and the other roller was cracked and about to break

It took 3 trips to ACOE Hardware, but I eventually came up with this stack of fender washers, normal washers, a 1/4 bolt and a nylon lock washer to replace the plastic wheels.

I got the bed slide all back together and it works pretty well (and no longer drags on the cushions!)

Nice work around. Keep an eye on it. You've changed from plastic to metal so it's going to wear different along the track it runs on. Don't throw the old piece away. You never know when you're out and about you might find something that matched the original more closely and you want to change it again. I've done it many times!

I pulled out all the grody cabinets today and I need some help from all y'all: Does anyone have details on how this kind of kitchen works?

The P.O. removed the kitchen. It looks like it used to telescope straight up from the base cabinet. It used to ride along 4 vertical tracks (The camper only has 3 of 4). My camper's remaining 3 tracks each have a burley clock spring that looks like it would lift the kitchen. There are latches at the top and bottom to lock the kitchen in place raised and lowered:
Looking down at wheel well:

Looking forward at brackets/track/clock spring:

Burley clock spring and bracket detail:

Questions for y'all:
1. Do any of you have photos or details for how the latching mechanism worked on this?
2. Do any of you have measurements of the telescoping kitchen height?
3. Do you know if the front track also originally had a clock spring? (thinking probably "yes")
3a. If yes, does anyone out there have a source for a replacement clock spring (and track)?

Thanks so much!
