I used to work as what was known as a Montage Monkey; we worked setting up the campsites for Eurocamp/Keycamp/Canvas Holidays in France, and would work alongside the mobile install team.
The Mobile install team would set up the mobile homes (what Aussies call cabins) for the season, including putting them on site (the delivery trucks would drop them at the gates) and they used Daihatsu Fourtraks for that that had 1 towbar on the back and 3 on the front - centre, right and left. Dirty great semi-homemade bars, that were fairly solid. This mobile homes were about 9' x 45', so a decent size to be put into place. Some of the sites/trees were only about 4' wider than the mobile home... needs a bit of a precision.
