I bought from:
Durnell's RV Wholesalers
The Original RV Wholesalers - RV Sales, RV Parts, RV Dealer, RV Super Store Dealer, 5th Wheel, Forest River
The first time I saw my trailer was when they delivered it.
The driver that delivered my trailer showed me work the slides. I have figured everything else out by reading the manuals or studying on the internet. I had 2 warranty issues in my 1 year warranty period. A leaking fresh water tank and a CO2 sensor. My dealer helped me get warranty replacement on the tank done locally. The CO2 sensor was replaced by the sensor manufacturer. My trailer is a Forest River. Forest River takes responsibility for the parts of the RV that they put together. Everything else is covered by the company that sold the part to Forest River (tires, chassis, suspension, stove, etc.).
Since my warranty expired, I have had a tire blowout and dealt with the Canadian distributor of the tire. I currently have a issue with the suspension and am working with Lippert (who sold the chassis to Forest River).
