I have a 2004 32' Mobile Suites GVW 14,000 lbs. I have swapped the original King pin box with a Flexaire. Currently the front of the 5th wheel is 4.5" higher than the rear from the ground. It appears that I can raise the King pin box two inches higher than it currently is which would bring the front and rear closer to even. However if I do that there will be only 5 5/8" bolts securing the King pin box instead of the 6 that the original King pin box had. Are 5 bolts adequate?
