How much weight can you safely store in the upper bunk of a Freightliner Columbia? If you gradually applied more and more downward pressure, uniformly distributed, on the upper bunk, what bad thing would happen first when the weight got to be too much? I've always kind of wondered what exactly is holding up those four corner platforms that support the upper bunk, and how much weight they can handle.
I'm asking about this now because I put a bunch of stuff up there a couple days ago as part of a move I'm doing. The very next morning a water leak appeared, with the water coming through somewhere up high on the roof of the cab. It was dripping down from the dome light area, and the blue vinyl cushioning on the ceiling was wet around the sides.
This was only from a heavy frost thawing out in the morning sun in the Seattle area. I'm heading to our CA terminal right now to have the leak checked out. Thankfully no rain is forecast today for CA.
There's nothing visible on the roof of the cab. I've hit tree branches up there sometimes, but never hard enough to puncture the body of the cab. I'm really worried the stuff in the bunk caused the frame of the cab to bend a little...enough to compromise the waterproofing in the roof. Seems too coincidental to be anything else. On the other hand, the total weight of the stuff up there can't be more than about 200 lbs.---I'd guess 150-175 lbs.---which doesn't seem like all that much. I tried to be careful and put large, relatively light items up there.
I might phone Freightliner to see if they can tell me what the weight specs are for the upper bunk...wasn't able to find any info on the web or in the manual that came with the truck.
upper bunk weight limit?

I weighed about 250lbs when I was going through training and I was up on the top bunk. Not so much as a creak or a sag. If it bent because of that stuff, there was already something else wrong with it. Some prior damage.
A possible answer was a bit of water seeped in and froze and that opened the gap up a little more to allow more water in. -
sound to me like it could just be condensation,i have had that happen to me before and thats all it was

Unless your truck has had the sleeper/ cab wrecked and repaired with new panel sections I doubt that the leak is from the outside. I would guess it is condensation on the inside of the sleeper, freezing to the condo roof over night, then thawing and dripping as soon as the sun/heat hits it. Same thing happens to my Classic condo sometimes.
During the winter we keep everything closed and warm, andy kind of water vapor from coffee to your own breath is trapped inside, gets hot and rises with the hot are from the heater to the inside roof. Hot inside, cold outside, high humidity inside, and condensation forms.
Try turning on your max a/c with your heat, or defrost , you have to get the truck into recirculate mode with the a/c compressor on, that will remove moisture from the air. Eliminate the moisture, and there is nothing to condense, and no drip...drip...drip... etc...
Give that a shot before you waste your day sitting in the shop. -
But reading your suggestion just now gave me a good idea: the truck badly needs a wash anyway, so I'm going to take it over to the wash bay and spray water up there to see what happens. If I can't get any water to come into the cab, it must surely have been condensation.
Will post the result of my experiment shortly... -
Could be either, wreck, condensation, or just a popped body panel. Never heared of the later, but could be. On really cold days when you turn the heater on , after the inside has been sealed up and cold, you would be amazed the amount of water you can get dripping. lol.
Let us know. -
Shortly arter I started driving I didn't know how to keep my weight down, went from 275 to well over 300 and my columbia held up great

i had one of those high top removable sleeper thingys b4 i bought the lowtop sleeper for my '95 fr8liner fld 120............and when i just got the truck i only slept on the top bunk...........around that time i weighed roughly 250lbs.....and it(the bed) supported it(my weight) perfectly..........i mean, which trucker weighs less than 200lbs???? i think it should be mandatory tht your weight as a driver be 199lbs up(LOL!!).......that bed would support 500lbs if it had to........probably just condensation or something(or maybe all those trees u hitting
_ lol

It's condensation, I had the same thing happen this week, after being in several weeks of constant below freezing temps, and a good bit below zero. Just the condensation from your exhaled breath creates quite a bit of moisture to freeze. I've been in snow storms on the inside of a tent while winter camping, nothing but condensation freezing to the roof panel, until you bump it in the morning and it all comes down.
