So worse case scenario is that the heli systems will see 3g loads, which can be magnified by either undamped trailer suspension or any mounting system! Even worse is that a running gas turbine will have higher rotational inertia, so when static may rattle away at it's bearings on a trailer...
Maybe a giant "baby bouncer" supporting the rotor hub? Landing Oleos can be thought of as very soft overdamped suspension, so will help.

Australian National Helicopters at Alice Springs Airport, in NT Australia have a pretty good set up if my memory serves me correctly.
I saw them towing a B47 Soloy with a F250. The trailer itself supported the aircraft on some sort of airbag self leveling suspension. If you don't know what the roads are like in the NT, well they are pretty crap, apart from the main highway most of the roads are gravel or dirt, and aren't graded that often. Really, if you are looking for a set up for an Ag work, it might pay to give them a call. I know they didn't have any problems with the aircraft from it being carted around on the trailer.
Sorry I couldn't be of anymore help.
Try looking up Australian National Helicopters on google australia.

I have pictures when we would transport a B47. Blades off. I have seen trailers with the facility to ship with blades on. If you let me have your email address I'll send some on..

As far as I know, all turbine engines should be transported by air ride transport, Piston engines are less susceptible to the brinelling damage which can occur to turbine bearings if transported on a non air ride truck.

Hi
The game translocation industry in southern Africa has been using trailers for well over 30 years to move their H300s, R22s and E280s between jobs without problems.
The suspension is the most important. The best I saw was a trailer using the rear cantilever suspension off a VW Combi.
Blades are supported. On the H300 two blades are folded forward. On the Enstrom you have to remove them (it's a pain).
I would have to dig to find pictures.

The Bridgemary estate in Gosport, Hampshire, has wide thoroughfares specifically for transporting helicopters from RNAY Fleetlands to, for example, Lee-on-Solent. Probably a long time since they were used.

If you ask me, if it can fly, you fly it.

Flying long distance to a location just to do work makes it an expensive taxi.

There are advantages to trailering though. For example you can mobilise 24 / 7, day or night and in almost any weather! Also no flight plans required. Sea crossings are much less stressful too! and think of the component times you are saving on. Also if it breaks down you can recover it yourself! Probably take your own fuel too.

I have not filed a flight plan ever. Not sure I ever will. VFR only and 99% of that is in uncontrolled airspace.
If it breaks down? my do your ships break down that often? We have less than one day a year per aircraft down for maintenance.
look at the opportunity cost of putting it on a trailer.
If i finish a job in New York today, and want to bring it to job in Missouri (1000 miles away) I can fly it there in the better part of a day and be ready to work the following day. If I trailer it, it takes at least 2 days to load it remove the blades (500) truck it there and unload it. the few thousand dollars in component time is more than paid for from the extra day of work.
