Some other Keystone trailers are constructed with aluminum or steel rafters, that's not the case with Springdale.
Springdale trailers are constructed with wooden rafters. As posted above, they are not much more than 1x1 and 1x2 spruce that's glued and stapled together to form an arched rafter. Over the years moisture, twisting motion from towing, walking on the roof and decomposition of the adhesive will cause the rafters to "weaken". Additionally, as with any "mass produced product" there's no "sure fire way" to know that all the staples are actually "holding the rafters together"....
So, the less weight you put on any rafter, the less number of times you walk on the roof, the more you can "spread the weight" over a larger area, the longer your trailer roof will last.
