Hi: We are new to the board and pretty new to rving itself. We have been looking for a 99 newer class a with options and having a hard time finding models with chev vortex engines. Now comes the reason for this thread. Most of the models we have found in our area, the Pacific Northwest are powered by Ford trition engines. After talking to friend that have fleets of trucks, I find that they have a problem blowing out spark plugs, mostly 1999 and 2000 which is about the years we can afford. I know this subject has been posted before, but would like to hear of some people that havn't had trouble with the Ford engine. After finding out about this problem my wife says we would be unwise to go ahead and buy a unit with these potential problems. My mechanic says if I came in with blown plug he could have me going again in about 4 hours and $300. But if we have a problem it's not going to happen here. Any info will be appreciated.
