Actually you can. Click "unload" in the Advance menu and you get your 2-4 logs back. these are lighter than complete load.
But this is another way how to "cheat the game", yes.
Point of "how many logs should be in there" was already discussed several times and I have nothing new to bring in: The game is driving through the mud simlator, not loading simulator. And honestly, neither I want to spend half of evening just by craning in 48 logs, because that should be more real. I like tougher conditions in HC mode, but manual loading is one I will turn off happily, if possible.
One big load is quite probably for simplification of physic. Your computer will probably be set in fire, if you force him to calculate reaction of each log to each other logs, and the carriage and all of that for each bump on the road

I agree. But on the other hand, I rather see Dev team working on improving gameplay, adding new possibilities and such, than fighting (endless) war against cheaters. This game is (so far) pretty much opened, look at level of MODding. There are even people playing with DevTool enabled all the time! So again: enjoy your game in the way that suits you. Delivering "legitimately" is some sort of personal achievement that you can be proud of on your own...
But that could be just me as well
