We have a new 2011 3450 BC. We have had it since Jan. and NEVER used it...when dewinterizing and preparing for 1st use there was a leaky valve on toilet that made it unusable...after a month at dealership we finally get to check out all water related items including water heater which we now find will run on electric but will not light for use with propane...my husband has tried hundreds of times all day today to get it to light with no luck. The switch is turned on and no click or sound whatsoever..no indication of ANYTHING. Any advice? Please, tell me we don't have to take it in to the shop again..it was not a pleasant experience before and we bought the camper to work out of and we don't have another month to spend waiting for it to get out of the shop...we have to head out on a job!
