Thank you to everyone that offered feedback, we truly appreciate you taking the time to respond. We ultimately decided on the Voltage 3990 and we are deeply in love with this thing so far. We got an amazing deal because it was a 2016 model and our maiden voyage was essentially trouble free (master bath toilet was cross-threaded and leaked but an easy fix). We are super excited and happy with our decision. I believe the Voltage has come a long way over the years as we have been stalking this thing since they came out. Fingers crossed but know they ALL have issues eventually and feel like we have realistic expectations. Happy and safe travels!
