We are looking to purchase our first RV and have read and read on the features and options. The unit I am looking at has the V10 vice the new V8 and wondered what I might expect as a difference. Is the new V8 better? I will be towing my 2018 Jeep Grand Cherokee (4 wheel towing) behind most all the time. Anything I should particularly look for and questions I might should ask? Thanks in advance!
