I purchased a 2109 Dynamax Istata 5 30 FW 4 by 4 in July of 2018 and i use it a lot for work i have over 40000 miles on it in less than a year I had a few small issues that between Brian at Dynamax and the dealer we have been able to get totally resolved granted i did Most of it however it is hard to leave the coach for the dealer to work on. All and all it is by far the best coach i have ever had. The one before was a sprinter based Winnebago a 2015 that i put 200K miles on and had a lot of trouble with it. I think this coach will be far far far better and i feel like the factory support is excellent i would definitely not hesitate buying another one.
