If the UK has not already done so they will be switching to Ultra Low Sulfur Diesel in the near future as the next round of emission hikes goes into effect. The US has pushed back their roll out date to sometime around September of this year, although some places already are using ULSD such as the Seattle area.
I think using a good lube add is important as the ULSD is very poor in lubricity. Otherwise you shouldn't notice any major differences. I would bring a couple of spare fuel filters just in case you can’t find them easy and get a bad tank of fuel (wet or dirty).
What kind of registration hoops do you have jump through to get your US trucks legal in the UK? The only experience I’ve had in the UK was with equipment that was sold in the UK.
