I don't have any blocking at the front and don't load it to the front.
I've not heard of anyone getting away with this. Properly adjusted tie downs should pull the camper into the front of the bed, and relying on mats to keep it from sliding forward during hard braking seems risky. If the camper cannot be loaded all the way forward, suggest making blocking job #1.
I'm presently running a short bed camper on a long bed truck. Blocking was easily achieved by building a frame out of 2X8s and screws. If you don't need this kind of footage, just stack 2Xs until you have the distance needed. Side blocks can then be added to the front block to stop any side to side motion at the front.
