Just got word from them that the computer estimated weights are correct for our 2017 19'. The GVWR is 5000 lbs.
That explains an allowed loaded weight over GVWR - it's not, because the GVWR is higher than it was. The base dry weight is probably different from the published 2610 pounds, too... maybe by substantially more than the slight frame difference would cause.
This is the sort of situation which I find really frustrating. People have been purchasing 2017 model Escape trailers for ten weeks, and the published specs are still not right. Now the only thing that we can be sure of is that none of the weight or weight rating numbers can be trusted.
I don't know what is changed to go from 4000 to 5000 for a 19'. Maybe someone else does.
The GVWR of any vehicle is limited by several factors. In trailers, it is mostly the axle capacity and the frame strength. The Escape 19' has two Torflex #10 axles which are ordered with the internal rubber trimmed to suit a lower load than the maximum for a #10 (which is up to 3,500 pounds), and coordinated with the GVWR. To have a 5,000 pound GVWR, they must be ordered for a higher load (more rubber)... likely about 3,000 pounds each (instead of the current 2,500 pounds each).
The consequence of higher rating for the axles means that for two trailers of the same total loaded weight, the one with the higher-rated axles will be stiffer and ride more harshly. If the new trailer is heavier, then that extra stiffness is needed to maintain the same ride.
The frame structure of the 19' is already essentially the same as the 21', so it presumably has more than enough strength for a 5,000 pound GVWR.
Thanks!
I always thought the GVWR (4500#) on the original 21 was pretty conservative considering it sits on twin 3000# axles, but I understand from reading here that in some states higher GVWR gets you into additional licensing requirements.
Licensing may be an issue, but it is not the reason for what looks like a mismatch between the GVWR and the axle capacities. Escape uses Torflex suspension (axles). In a tandem (two-axle) configuration the two axles do not evenly share load between them, so every time a wheel hits a bump that wheel's axle carries much more than its share of the load; to avoid overloading, each suspension (axle) needs a rated capacity which is significantly more than half of the total for the trailer. Reace selected the axle capacities for the 19' and 21' to properly allow for this, following Dexter's design recommendations; in the 21' this means 3,000 pounds for each axle rating, and 4,500 pounds for the trailer rating.
