On all other models, that slide carries the kitchen. Counter, cabinets, cooktop, microwave, 10 gallon water heater. Heavy stuff. I donít know what the weight capacity is for the slide, but it is a very robust design. Iíd guess the kitchen slide carries 500-1000lbs more than the dinette slide.
FWIW: WRV recommends deploying the jacks prior to extending the slides.
