Bought a 2nd hand Elddis Jetsream 2000 last month and took it out for the 1st time this weekend. Noticed a crack in the shower tray that we didn't know aboutwhen we bought it. Dealership have said they will check to see if it is covered under warranty. If it isn't does anyone have an idea of cost to replace as we know that damp and caravans do not mix!
