Sorry for the delay I didn't notice the message. Mine was on coils when I bought it, I fitted Koni Heavy Trax shocks all round on the medium setting , these are probably over the top, so Terrafima would probably be ok. Mine is firm and not such as smooth drive as my friends RR on air, but I find it ok and quite like the feel. I don't tow a caravan so I can't help on that. Tony
