Don't believe any of the highly inflated towability numbers the various manufacturers are flogging these days. It's almost scary what they are doing. The "1/2 ton towable" label has been around for a while and now I see that KZ is using a "1500" and "2500" designation on their trailers for 1/2 and 3/4 ton tow vehicles.
KZ is now listing a 34' Durango 5th wheel with a dry weight of over 8,000 lbs as being suitable for a 1/2 ton. I'd like to now how any 1/2 ton truck can handle that, even with a HD tow package. Am I missing something? Our 3/4 ton truck would not even be able to handle this trailer on the basis of payload. I also see that KZ seems to have lowered the 12K+ GVWR for this (or similar 34' model they have) to 10,800 lbs GVWR. I am guessing that this is to make it appear more tow-able by a 1/2 ton? I am pretty certain if this is the case, the loaded weight of the trailer will be pretty close to the 10.8K GVWR and not leave room for a tank of fresh water even (happened on our current trailer). And what about the RAWR with this trailer on a 1/2 ton?? They, as are most (or all??) are silent on payload and RAWR limits and calculations.....
The trailer manufacturers are all playing a weight numbers game and regretfully you have to go onto forums to educate yourself.
