mopsie, welcome to iRV2.com. We are glad to have you join us here and we look forward to reading of your adventures and experiences. I am sure you will get plenty of help with this questions if we ask it in a better area. Tiffin makes good products and I am wondering if the 04 Horizon is new why it is still around. You could ask this in the MH General Discussion area. Good luck and enjoy the website.
