07 Kountry Star 3910 vs. 08 Kountry Star 3910
There may be a difference in engines been though they are the same size. I think the 2008 had a 400isl and might have the new EPA requirements. Not so sure the 2007 had the same engine, only the same size. However, they made a few early 2008 with the pre-EPA requirements. Unless I am wrong, I believe the new EPA requirements had a negative impact on MPG. Both 2007 and 2008 have experienced exhaust manifold warping so you may want to inquire whether either had it replaced. The replacement cost was close to $1,200. Could be that one or both have had them replaced. Symptoms are a noise similar to a fan belt squeal.
