Not raining on my parade at all.
I chose our 2014 Lifestyle over DRV and that was before the Thor buy out of DRV. I was not impressed then and I sure am not now.
Since the Thor buyout of DRV, the quality (or lack of has suffered) and customer service is poor. Many 2016 and later models have leaking slide rooms. I'm basing that on many, many posts from DRV owners on various forums as well as my own observance at the Tampa RV show the last 10 years.
Every brand has issues with some of them. But I'm glad to have the LS over the DRV unless the DRV were to be pre-2014.
