Not a camper trailer but.......
Got my HC licence 20 years ago. Drive a couple of empty rigid trucks soon after (with roadranger gearboxes).
Got my b double licence about 10 years ago, in an automated manual gearbox Scania. First time I had driven a loaded "proper" truck since I got my HC licence. Then nothing but light vehicles and the local cfa fire truck.
Have driven a couple of empty, folded up log trucks in the last 6 months.
Yesterday I bit the bullet and jumped in one of these, in the dark, at 3am.

With the regular driver asleep in passenger seat, hour and 1/2 out to the coupe, back it down the dozed in coupe track (1 foot clearance each side to the table drain where I nearly got the Hilux bogged a few days before). Still in the dark. At least that bit was still fairly straight.
Load up to 68t. Strap up. Power divider and cross locks in. Drive tyre pressures dropped from 100 down to 40psi, and ease the clutch out. Don't break traction!!
Out the coupe track, a few tight corners, and a km or so along a fire break because it was less boggy than the actual track, then a hard 120 degree corner onto the single lane bitumen road, across a single lane bridge, on a blind bend, on a hill. 15km to the highway hoping I don't meet anyone coming the other way.
Through a few towns with multiple round a bouts etc and back to the yard where the regular driver woke up and jumped in the drivers seat and headed off to Geelong to deliver and I headed to office to catch up on 20 missed phone calls etc of my normal job.
4 hour round trip and i didn't hit any kerbs or cars, although the gearbox will probably never been the same😁😁
