1987 Coleman Columbia Project

RE: 1987 Coleman Columbia Project
It has everything to do with the bigger tires. I have towed significnatly more with the Cherokee - using stock sized tires - and it barely noticed it.

So now I'm trying to figure out my options. I'll be going back to normal sized tires for this winter anyway.

As much as I don't want to go to a weaker front axle, I am thinking I am going to switch out to a TJ Wrangler 4 cylinder front axle. It will have 4.10 gears. Short term it will work. Then I will try to find a bolt in 4 cylinder Cherokee axle or get a ford 8.8 in here - which one can find with 4.10 gears and rear discs.

If I end up with (yet another) Chrysler 8.25 hanging out ready to go in I'm ditching those horrible-3rd-world-garbage brakes. I should beable to use a setup out of a Liberty.

Cooling system seems to work, though. Had no problem towing the trailer in the heat with all the junk and the AC on. Never got above 220 on the way up or back.

Also - the storage in the popup can't really be used. It's all behind the axle. Had a lack of tongue weight on the way up and had a bit of trailer sway.

Why not keep the hp d30 you have and swap in 4cyl yj gears. For the back, I think Durango and dakota used the 8.25 so you could check them for 4.10s or go the 8.8 route.

I could use YJ 4.10 gears and carrier, but I'd still have to pay to have the new gears set up. Mike at Smittys is about $300 an axle to set gears.

If the width was the same between durango/Dakota/Cherokee (It may be)- it may be as simple as swaping shafts abd backing plates to get the correct lug pattern for the 8.25'' axle.

Found a set of 4.10 axles in RI with very little rust for $500.

It's a non-disco front and 27 spline rear.

Debating on getting them.

RE: 1987 Coleman Columbia Project
Nothing has happened to the Columbia lately. It is put away for winter.

I am thinking of picking up the 800 watt Harbor Freight generator for it. Has anyone had any experience with it?

My spring plans are:
  • Remove stove and cabinet - make stove able to be used outside
  • Refill Propane tank
  • Add 1-1/4 receiver to rear somehow ... there's no bumper or frame back there
  • Make battery box on tongue with 3 or 4 batteries, run inverter from it
  • Tie in 12V to existing 12V without having the DC/AC power converter running all the time
  • Add Generator to tongue
  • Recaulk
  • Go back to spring-under for Focus purposes
  • Modify internal storage so I can get to it without popping up the popup.


The generator will just be used to charge the batteries.

RE: 1987 Coleman Columbia Project
So making progress.

Have a small generator (the 800w HF one - should be perfect for charging batteries). Still need to figure out a battery bank situation. Would like to avoid car batteries, but they are cheap and easy to tie in together. Also will need a larger capacity battery charger.

Tonight I picked up a small compressor-style dorm fridge. I was originally planning on a thermoelectric type cooler but the price was right on this one. While it won't keep everyone's beer cool, it'll keep food good for a few days. The compressor fridges do work a bit better as they are a *real* refrigerator.

It only draws ~135 watts when running.

I am going to keep the stove in it. I only wanted to remove it to keep bears from wanting to get in - but for wheeling events and stuff it will be nice to have my own stove.

Picked up the battery charger today. Will be buying some Group 29DC batteries to run everything next week.
