Aimee,
It is a little late in the game to mention this, but this is important to me so I would assume it would be important to prospective buyers.
In all Specs for all models on the left column, you mention "4-Wheel ABS Brakes". That is good. But it would be better to mention "4-Wheel ABS Disk Brakes". The word "Disk" is something worth noting. Anyone with an older motor home will have rear "drum" brakes. They may not realize the E350/E450 and Sprinters have disk brakes all around. Given that disk brakes are better brakes, that is a good thing to point out.
