Very low cargo capacity

I've been looking at quad bunk model travel trailers with the separate room in the back and have noticed that some of the lite models have a very low cargo capacity. Some as low as 1200#. It seems like owners of these units would likely exceed the cargo capacity since the owners are probably families with kids. My Jayco 28BHS has a CCC of 2200#. Do you think the CCC on these lite units are being exceeded or are families with kids traveling very lite?
  • The CCC numbers now are a different breed from the older RVIA numbers. The feds (NHTSA) developed their own standard, which manufactures are required to use.

    Under the new standard, water counts as part of the CCC - in the old standard, it did not.

    For example, a trailer with a CCC of 1200 lbs that is carrying 40-gallons of fresh water has used approximately 330 of the 1200 lbs. With the older RVIA CCC, the 40 gallons has not used any of the 1200 lbs, because the weight of a full tank of water had to be accounted for before calculating the CCC. In other words, a 1200 lbs. CCC with todays standards would be about 870 lbs. with the older standard.

    Note: the number of occupants had no direct bearing on the CCC of a trailer, since occupants should not be in the trailer while it is traveling. The weight of the occupants in a motorized RV counts as part of the cargo.

  • To the original poster..I agree with you. A quad bunk house with only 1200 lbs of cargo capacity is going to be a problem with a family and all the gear.

    In contrast, we have an Arctic Fox on order (not a bunk house) that has a cargo capacity of almost 3200 lbs.
    It's all about the stoutness of the frame, and running components - axles, wheels, tires, etc.

    Not necessarily ... manufacturers often use the exact same suspension components (axles, tires, etc) across an entire lineup, whether the trailer in question has a UVW of 3500 lbs or twice that, in which case the smaller, lighter trailer will have a much greater CCC. Such was the case with my own KZ Spree which wore the same suspension as much longer, heavier Sprees in the same line up - great for me as I had well in exess of a ton of CCC whereas friends with larger models could barely get by with the available CCC and remain within the trailer's ratings. The same holds true with my current 19' Coachmen Freedom Express - over a ton of CCC but not anywhere near as much with some of the larger models in the same line up.
  • It is obvious that a family would be close to maxing on a TT with a low CCC. Normally a low capacity is due to smaller, lighter duty axles. In this case, a trailer loaded to max, would be more apt to experience bent axles, suspension problems, lack of braking power, and tire failures.

    JMO, as it is possible to never have any issues, just some things to keep in mind.

    I'm not a fan of `lite' models. To reduce the weight either the strength has to be compromised or the materials are very expensive to be strong but not heavy eg. carbon fiber.
