I use Waze all the time in my car. I have a love hate relationship with it LOL. I can always just go with the Waze alternate recommendation if there is a major problem and be cautious of the unknown, knowing I can always easily turn around. I'll always know where the tunnels are and just have to watch out for low clearance - this is one of the reasons I love my small(er) sized RV and I love not towing anything. You'd have to pay me a lot of money before I would ever tow anything with a MH. Had a couple of TTs and would never do that again either. It's just too stressful for me at this point in my life. I want as easy as possible and the less technology the better. I sound like my mother now but it's all just too much - everywhere every minute of the day. I really just don't need it (other than my phone and laptop, of course).
