I also forgot to add you can but the Goldhofer tyres & rims separately from
http://translate.google.com.au/trans...%26prmd%3Divns (when you go to the site look in NEWS for details) if you require a slightly larger tyre than the normal Carson low loader one, also you can get the air bag suspension /axle from this site if you want to scratch build a trailer to suit your own purposes, one other thing to note with the new suspension it give you the option to mount the axle over or under the travel arm..
