Relative to a particular Syncro Westy only, but worth considering:

"I have weighed the four corners of my Syncro Camper with some
automotive bathroom scales I got.

In an "empty" (*) state (for me) weighs ~5300lbs as follows:

LEFT    RIGHT   LBS.
20%     25%     FRONT
30%     25%     REAR

The weight at the left rear is fairly massive compared to the left
front.... almost a 50% increase in the back left rear vs. the front left."

Not my van, but similar to it.
