I have tried lowering the windows for a little bit and even have opened the sun roof to help eliminate the extreme hot air inside although, this still will not get the air cold enough or keep the air cold inside the Mega Cab in hot summer weather. It also will not do the job even if I keep the recirculating fan on continuously. I have owned alot of cars, trucks and SUV's but never ever have I been so displeased with the "mega Cab A/C". Like I've said before, if you live in a cooler climates it's probably ok - but absolutely terrible in warm to hot climates. I thought that A/C was to be used in hot weather not cold weather. I'm glad to see that your pleased with it in your cool climate by the beach but when I purchased my truck they didn't make me sign a discloser stating that I had to live near a beach. Sorry if this comes over a little strong but if you lived where alot of people do live - I believe you would have an entire different outlook on the "plagued Mega Cab A/C. If you do alot of searching on the internet you will find countless owners that have this same problem and Dodge will not fix it! They just say "IT'S NORMAL". This is there way of saying it will cost too much to fix the nationwide problem.

If you're looking for the axle type, ratio, and size, there should be a label affixed to the inside of the glove compartment door. If you are looking for the axle load weight, that should be on a label found on the door pillar.

For towing a 5th wheel with a shortbed you'll likely need to get an extension kit for the trailer. "Popup" makes one that seems to be pretty popular. Check out their site to see what I mean. (Just search 'popup 5th wheel extension'). The problem you'll run into is that when you make a sharp turn with most 5th wheel or gooseneck trailers the corner of the trailer likes to crush your rear window. Not such a problem if you never turn, however if you plan on going in anything other than a straight line, you'll probably need one of these adapters. Also, If you try to get around this by mounting the hitch too far back in the bed, you'll affect your truck's ability to steer, another unfortunate problem with the shorty bed. Aaaah, these mega cabs are full of issues, but I still love mine!!!

What year is your dodge truck? Has this problem been fixed on the 2009 mega cab or crew cab that you know of?

I have the 6.7L Cummins with all the emmisions crap on it. When the warranty runs out I want to take this stuff off (don't tell uncle Sam). Right now I have 40K miles on the odometer and I'm getting 14-16 mpg. I want to get 20-26mpg like the old 5.9 Cummins. Anyone know how I can improve my mpg right now???

I have a 2007.5 Mega cab 6.7L and live in Dam Hot, Texas. I don't seem to have the problem you are experiencing. I always keep a blue-point thermometer stuck in the front center vent, just something I've always done. The air coming out is a cool 36-38 degrees with decent flow and it cools relatively quick. Note: I also have a mild "legal" tint job. Is it possible something has been sucked up the intake on the passenger side? I had an 04' Ram dually 4 door and had no problems until a piece of cellophane got sucked into the return and was blocking flow over the ac coil which caused it to freeze up lowering flow even more. I would have to turn ac off and leave fan on for 15-20 minutes before it would thaw and start flowing again. Hope you find the problem/fix as no ac definitely sux.

Some early build Mega Cabs had a problem with insufficient cooling capacity, and I think the fix was to increase the evaporator size as well as some internal design changes.
