We have the same arrangement on our Triton 420. The nose weight seems more dependant on the number and size of gas bottles in the front locker. For example with two 6Kg propane bottles in it (both full ) the nose weight is 90Kg +. Its easy to move most heavy items close to the axle but not the gas. Best thing is to measure your nose weight in stages as you load---put the functional necessities in first (don't forget the wine or beer) and then the non essentials. Best not to get the OH involved at this stage as they have a funny idea what is essential.
