I would think that service would work the same as it has for me. I purchased my Fuzion from Holman nearly 500 miles from where I live. I had a few small warranty issues to be addressed and the local Camping World dealer gladly handled that for me. Every dealer that sells your brand is obligated to do warranty work for you regardless of where you purchase from. Although they have to do the work, there is nothing forcing them to provide prompt service or to be easy to work with.
I would pose the question to RV Outlet prior to considering them for your purchase. I asked the same question of Holman and their policy is for you to call them first and they will facilitate a service visit with a dealer that is local to you. Unfortunately I have a Keystone dealer located less than 15 miles from me, but I travel 45 miles for parts and service because their service department is even worse than the sales department!
