Weight listing

Our '07 Trail Cruiser 21' ultralight's dry weight as posted inside a kitchen cabinet was listed around 2,900 lbs. As we shop now for a new 23'-25' unit I see weights are appreciably higher.

Has the Gov mandated a different formula for weighing RV's since '07?

    Full propane is included in the weight, water is not. Batteries should be included if manufacturer installed, but I think dealers add them in most cases.

    If the vehicle is a recreation vehicle trailer and is equipped with a propane supply, the weight of full propane tanks must be included in the vehicle's unloaded vehicle weight. If the vehicle is a recreation vehicle trailer and is equipped with an on-board potable water supply, the weight of such on-board water must be treated as cargo.

    Water isn't included in the dry weight but the weight of a full tank of fresh water is listed on the yellow tag.

    Sort of, in 2009 regulations required true and accurate weights to be used. Prior to 2009 many manufacturers weights were pure fiction.

  • No. The mfgs are finally using honest,or somewhat honest numbers. The yellow tag, or what ever color it is this week lists the scaled weight as it rolled off the assembly line. Still meaningless though as it does not take into account, water, propane, or batteries. Guessing is a really poor way to know how or if your loaded to the max. So instead and to be on the side of caution always look at the GVWR from the tag at,the trailers left front corner. Use that as your guide and you will always be on the safe side of things.
