Four pallets if you’re double stacking.
You can move fourteen 13.6m trailer loads worth of pallets with just thirteen 14.6m trailers. Given the fuel penalties are next to nought to the operator you could be saving potentially £400-£500 for every 364 pallets you need to move if you’re using them for trunk runs.
Don’t actually understand why they cant put all the wheels further back rather than one set way behind which has to messup the pivot point.
Because they’d cut corners even worse than they already do and they’d need even more manouvering space. I’ve been unfortunate enough to drive trailers with axles right at the back in the 1990s and they were terrible for manouverability compared with them being in the “normal” place and this was just with 40ft trailers.
