My wife and I are looking at the HitchHiker Discover America series in a triple slide to replace our current 5th wheel. But I had someone tell me that the aluminum wall framing would not hold up as well as the wood wall framing on either the HitchHiker II or HitchHiker Premier series. Any experience or recommendations would be appreciated. Our current fiver is a 1998 Mobile Scout 27RKFS all aluminum superstructure which has had absolutely no structural problems.
