Your dealer is right. 14'boards are what my HydroHoists have and I've had 353's,382's, a 370 SS on them . Most of the weight is in the rear anyway. Some of the larger lifts,tho not the 8800# have a v-block on the front but you don't need it. Most of the HH dealers are pretty knowledgable, I would go with what he is telling you.
