I am going to buy a 2015 Coachmen 21RS. Any comments on getting a Ford or Chev. The only difference that I can find on the Coachmen description is that the gross weight for the Chev is 14,200 lbs and ...
Try both, see which one you like more. Either chassis will easily out-last the coach under normal conditions.
If it were a maxed out class C (like one of those double slide 32-footers) I'd say Ford without questions, since its chassis it is heavier, and the motor is bigger. For a small coach, definitely driver preference.
Also.... Check local Ford and Chevy dealers, and make sure you can service the chassis you choose. Not all Ford dealers will do motor homes, and even less Chevy dealers.
