No problems with the radiator but that would be a spartain issue if I did(same as the zepher). Why must you be so defensive?I have no vested intrest in Entegra or Tiffin. I have only posted my experiences with both. What use are tnese forums if people do not honestly post their experiences? We are not in a ford chevy endless argument but wnat is happening now.I owned a Tiffin 45lp and would still if it jad been repaired and not kept developing more issues each trip. How can some one decide weather to buy a new motor home if facts are hidden ? I bet on tiffin and was severely disapointend (I wish I had been happy would have saved $$)
