OP:
Were I to do it over, I'd go with a Jayco Redhawk. Greyhawks are beautiful but HEAVY. You won't have a lot of cargo capacity in them. All that glitz and comfort features come w/ a weight penalty.
Compared to my Minnie Winnie, I find the Redhawk to be infinitely more comfortable. I can't comment really on the build quality between the two (my Minnie Winnie has been good to me), but the Minnie Winnie w/o the Premier package definitely feels more rental grade. You do NOT get that feeling in a Redhawk.
However, my 2900+ pounds of cargo capacity sure does make me feel good when I'm rolling down the road.
