Forest River Berkshire

I bought one of their Class C motorhomes in 2013 and had problems from day 1. Took it back to the dealer and he did a temp fix on the making the toilet and faucets work. Still problems with debris in the water line (and not the tank). Seems like it was intentionally put in at time of manufacture. Also added three 108 amp batteries and cannot keep it charged as there is a continual large battery drain. The dealer, Mike Thompson RV, Fountain Valley, CA cannot fix it. Would never buy a Forest River product again.
