After negotiations with both dealers, we purchased the 2018 Jayco Greyhawk 29MV. It was a long and painful process (for me! Hubby loves that phase.).
In the end after hubby compared all the mechanical and utilitarian differences, there were two other features that were very important to us that were standard in the Jayco --- two AC units and MCD duo shades throughout.
The Coachmen Concord dealer did agree to add the shades and to upgrade the one AC - they advised that to add a second AC unit would entail rewiring and it would be cost prohibitive. But, I wasn't keen on retrofitted options. The walls aren't the thickest in these and realistic or not, I envisioned the heavy MCD blinds falling to the floor enroute. On the AC, we would still be left with only one unit (even if upgraded) - we live in Texas and travel West quite a bit and a working AC is paramount to our survival.
And, this is petty on my part, but the Concord dealer said they were not able to replace the metal blinds behind the stove due to Fire Code. In the Greyhawk, the window is not directly behind the stove, so not an issue and no metal blinds. (When I see those, I get that "no wire hangers" look on my face! LOL!)
Long story short, we go through PDI on Monday with the Greyhawk. We enjoyed our Rockwood Mini Lite TT and now look forward to continuing our journey in a motor home. Thank you for all the info and tips - everything shared was carefully considered.
