There are open-top containers available too, an iveco van wil happily fit into a 20 foot open top.
Vans are tricky on Ro-ro, a truck is better so you can really isolate cab (which you've stripped for the trip) from the box. Friends installed a big grill in their converted van which was bent out of recognition on arrival, contents gone of course.
The Iveco's a great beastie, takes one hell of a load. Mine (LWB with camper body) broke a spring in Ghana (not surprising considering) and I got a new set custom made in Accra for a song. Apart from that, brilliantly reliable, they still have a timing CHAIN, none of this rubber business. Injection's Bosch, turbo can be Garrett or KKK, just like most european 2.5l turbos.
The famous question of spares availability: having seen friends with a HDJ80 stuck for 3 weeks in Bam with promises of finding the part tomorrow in the market (from the Toyota dealer!) I prefer to pre-arrange with my local dealer to send parts by DHL if the need arises!
Weak point seems to be the rubber boot on the outside CV joint. Inspect, clean and silicone more regularly than the rest.
