Time for a new hot water system! However, we couldn't buy a replacement American-made, 23-litre LPG-only Suburban unit due to them being withdrawn from sale over potential carbon monoxide leaks. Fortunately, the team at Suncamper Motorhomes was able to install an Australian designed and made, 20-litre Swift LPG/electric unit, with minimal modifications. Incidentally, Suncamper Motorhomes (in Sydney's north) does general campervan and motorhome repairs and modifications at reasonable rates. Call them on 1300 416-854 if your RV is in need of some TLC and tell 'em iMotorhome Magazine sent you. Safe travels!
