I totally agree! Had I known earlier what my problems were, I'd be on the warranty issue as well. It's unfortunate that getting warranty work for poor workmanship is a hard battle to win. Forest River seems to fight any claims for warranty work; I"ve heard friends of mine with other brands have far more positive experiences when obtaining repairs.
Good luck to you!
