hi Bruce and Sue, You sure have made a good choice with Kedron AV2. Our Cross Country is beut having traveled fron Albany wa to Darwin back home via the Gibb River rd and to Tasmania, this past Jan-Feb with very little problems. On the water tank filling we did get caught out on how, to fill the darn thing with out getting blow back all the time, untill some frendly Kedronite in Kunnenura gave us the sullution. Buy some ridgit 10mm black tubing aboout .400mm long, which you shoud be able to push into your filler outlet elimenating any air bubbling back out. I have fitted a common hose type fitting to both hose and 10mm tube this works very well :thumbsup: good luck john and jol
