Weight distribution with a Hangover

I had this same problem with my old Class A,I put a storage pod Like this one on the roof as far forward as I could. I then went thru all the storage compartments and took out all the heavy things that I liked to have along like the jack, spare parts, oil even spare water,things that I did not use every trip but wanted to have along just in case.

I was surprised that I had managed to transfer 300 lbs forward to the front axle when I re weighed it.
