Hello,
I have a 2017 M29 so not same exact model but built the same, so far we love it and after shopping around, it is for sure the best bang for the buck! Love the full laminated walls floor and roof, (although we have it in for warranty service right now for leaky bunk windows. But after researching there is not a manufacture out there without complaints or issues and CW jumped right on the problem) ill let you know how I make out!
Everything else is as expected or better for what we paid for this unit (queen mattress is not the best so we added a mem foam topper). Very well equipped for the price as well, slam baggage doors with led lighting, led lights through out the coach, enclosed underbelly, black tank back wash, quality chassis, wheels and tires, axels, brakes...on and on! I only added a power tongue jack ($136 at harbor freight) to make hooking up the WD hitch less of a chore. It tows, tracks and stops beautiful (2009 GMC Sierra 2500HD Equalizer WD hitch). The bumper caps suck...get new ones, almost lost my sewer hose.
Find a Camping World that that has multiple M27 units in stock, look at them all and pick the best or freshest off the line, don't let them choose for you! I think TV mounting options in the M27 are limited to smaller screens in off centered areas for viewing. If weight and a little bit more cost are ok, the M28 is nicest lay out, dual slides, a center island and huge rear bath! and I would have gotten it if we didn't have kids...and probably will when they are done camping with us!
Good Luck!
