I don't have any issues legally transporting my E27. The Iveco Daily tipper is a great tow bus, and plenty of space even for things like the grading beam. Payload around 900kg so plenty of buckets, grab and ripper. It has a nice low 1st gear which is brilliant for towing. The Ifor GH1054BT was a fantastic purchase- just big enough for every machine I have save the 3t dumper, and a payload of 2840kgs. So perfect for the E27, the multione 8.4 fits on it quite happily with a grab or 4 in 1 bucket on it, and I even manage to squeeze my Kubota B2530 with mid mount and rear collector or flail collector on by reversing and using the bucket rest forwhatever is on the linkage. Just have to take the side hose off if the mid mount and collector are on it. The tie down points and side step are great too, make lashing down a pleasure rather than a chore.
I'd never want to go less than a full fat 2.7t machine unless I needed the compactness of a 1.9t. I'd say that goes doubly for doing the sort of work you do. Perhaps review your transport arrangements instead?
