Mark Obtinario is well versed on all things related to extended wheeled vehicles.
We were lucky because we had a full year of RV ownership before we enrolled. Few students probably take RV 101 right out of gate and like them, we waited until we felt it was necessary to get expert RV driving advise. Especially help with backing up our RV!
Day one was incredibly helpful because I am a terrible “backer upper”. 
You’ve heard the saying “in the Nick of time”? Only an hour after day one training, I had to back out our 35’ RV out of a Best Western hotel that had ZERO turn around capability.
We were ready and in the “Mark of time” my wife and I surprisingly backed up our 5th wheel and truck successfully into the collocated two-way road in front of this hotel.
Without any doubt whatsoever, Mark’s training was vital to that success. We’re grateful for his superior truck and 5th Wheel RV backup training.
Day two training was important as we navigated busy streets and a lot of mountain roads.
My wife and I got a lot more out of day one training – that’s not to say day two wasn’t important though.
Please Keep Mark in your “Roledex” of talented RV trainers. He’s REALLY good at this!
With respect
