Ive just fitted a Exedy Safari tuff clutch to our cruiser, awsome clutch and no shudder.Ive never heard any bad reports about one.
Cost for clutch was around $750.Not sure on fitting costs as I fitted it myself.
What ever you go for just make sure it's a heavy duty one
4terrain heavy duty clutch, the clutch itself cost $800, $75 for a flywheel machine, $55 for a new spigot and around $400 for labour, all up around $1300. Its plenty of cash but like you said once its done, it wont need to be done for many k's and you wont have it in the back of your mind.
This article also mentions that Bundaberg is caravan unfriendly. Caravan Parks are expensive and lack grey water disposal. Caravaners tend to be more self-sufficient now and prefer to stay in low cost showgrounds or bush camp settings.
