We are in the market for a new travel trailer and are considering a 2007 K-Z Frontier. We almost bought a 2006 K-Z Sportsman (used), but backed out of the purchase because the RV's under-carriage was loaded with rust. The 2007 Frontier has never been used, but when I crawled under it yesterday, it too was rust covered. Randy, who runs the RV center where we store our trailer said he'd never seen so much rust on a 1-year-old RV.
Anyone else had this problem with K-Z products? We plan to keep our new trailer for at least 10 years, so rust is somewhat concerning to me.
