Hi, can anyone point me in the right direction. Entegra pointed me here; and Thetford doesn't answer phone. <br/><br/>I currently have a luxury 2014 Entegra motorcoach with a round Tecma toilet by Thetford in master bath.<br/><br/>Hinges mount to vertical edge behind the seat. <br/><br/>I want to replace with a quality elongated toilet that utilizes regular toilet seats, so I can mount the bidet...
