Looks like your CT13 is basically sound and has most of the original equipment, and you got it at an exceptionally good price! I envy you the original plastic cabinet covers (mine are not-as-nice replacements). You'll be busy for a while fixing and upgrading everything, but rest assured, it's fun and safisfying and you will enjoy the fruits of your efforts.
Some food for thought:
I see you have the original evaporative ('swamp') cooler. Best thing I did on my CT13 was removing that cooler (which only works effectively in dry climates and is useless in midwest's humid summer heat). I sold the cooler on eBay for $50, installed a much more useful FanTastic Fan, and gained a couple inches of head room in the process.
Having no small contortionists capable of using the gaucho bunks, I swapped out it out along with the multiple cushions. That made the front bench roomier and more comfortable after I had new front cushions made.
The OEM ice box is too small and awkward to use, so we just keep an ice chest in the van. I removed and scrapped the ice box and built in a food storage pantry that is much roomier and more useful.
I installed vinyl floor covering which is easier to keep clean than carpeting.
Our stove exhaust fan and heater fan are both noisy, too. But we use a small electric heater wherever we have hookups, and the FanTastic Fan does a good exhaust job.
We swapped out the heavy original dinette table and use a very nice folding table instead - plenty big for the two of us and no sweat getting in and out of the seats. The folding table is sometimes useful for outdoor dining, too. We hang the table on the back closet wall when not in use, so the back benches are open for lounging. Added a couple of wall-mount reading lights
back there, too. A couple of light
pine boards support the bed at night. We use a double sleeping bag for bedding, just roll it up in the morning and stash it across the back seat with the 2 bed boards underneath.
We've put 22,000 miles on our CT13 since we got it, and the pleasures have more than paid for it.
I recommend buying the copies of UHaul
manuals from Ray Horner at the UHaul
website. They're useful when doing repairs or modifications. Other than that, I strongly suggest caveat emptor
in dealing with Mr.Horner.
If you have any questions about your UHaul, please feel free to send me a PM.
Best wishes to you for many happy miles ahead!
