Bought an Autotrail Apache earlier this summer first motorhome we have had for a long time. Trying to get used to doing everything correctly and failing! Think we need lots of advice hence joining this forum! We emptied all the water systems and the van now has a terrible smell like rotten eggs. One of your threads says its bacteria growing in the hot water tank. If we chlorinate the water wont it just happen again when we empty the water to winterise it? What else should we do to prepare for the winter? Thought it would all be fun...its really an exercise in problem solving!!!!
