If mill weight is an issue you can minimise the need to carry a big saw and mill by using a wheelbarrow, or better still adding detachable wheels to the ends of the mill rails.
Like this.

I use pump up wheels taken from a $20 hand cart because they make it much easier to manoeuvre in soft soil and sawdust
I also leave the 60" mill rails on the mill even when using the 42" bar.
While this takes up more room it does make it easier to manoeuvre onto the log rails,
The wheels are attached and then the mill is picked up at the trigger handle end and pulled along behind you.
I make good use of this because my shop at home is 60 yards away from where I park my vehicle and I only have a narrow wheelbarrow access down the side of my house to the shop.
Wheels means a ramp can be used to load and unload into my van.
At the log, if the log rails are firmly locked to the log and not too high off the ground the mill can be parked alongside the log rails and pulled up onto the log rails.
This is aided by adding HDPE strips to the underside of the mill rails
Then the wheels are removed and reattached at the other end of the log but often I just leave the wheels on as they help to balance the weight of the power head and add more weight to help the mill slide down the cut.
The full length mill handle parallel to the rails also extends outwards to act as a 3rd leg.
Notice how far away the full length handle is away from the mill rails - this makes it easier to hand file the cutters from that side.

The 3rd leg allows the mill to stand on end on a firm surface - this makes it much easier to clean.
