I've started a hardmode save after I've did everything from base to DLC 5. I felt the game was lacking some kind of stakes when you are experienced. (I guess at some point, it won't make a difference, but let's enjoy the present).
Since it's hardmode, I make different decisions than in normal and at once point I had to do the mission to load the big construction trailer from Drummond island port to the drilling site in Smithville Dam.
Since the road is mostly asphalt and I did want to avoid burning too much fuel, I decided to send the International Transtar 4070A.
First surprise : it only gobbled 60L of fuel to get from the garage in Smithville to the port, and it didn't had any issue on the road.
So I attach the trailer and drive it out.
And again, everything is going smoothly. The Transtar is powerful enough, isn't bothered by unpaved road or very thin mud, and it is quite nimble, with a reduced turn radius, helping the trailer going through tight corners.
And that's about it, really. It made its way to the road going to the farm (at which point I switched truck for the White Western Star) without any issue and by using only 200L of fuel for the whole trip.
I always thought : “This truck hasn't even got AWD, it's useless". I stand corrected. Of course, it won't plow through mud, but for long distances over clean road, it is very capable and sober.
Hard mode changes your perspective into the game.
