I just wanted to let you know My wife and I are very pleased to have met Mr. Dinko Bosnjak. He was a very nice salesman who was not pushy in his approach to selling us a trailer. He was informative and helpful all the way through the process. We see your new location will be very close to our new home. -

We had a walk through on our new Newmar with David and Lucas (Meridian store). They explained everything on the RV and even shared their glasses to watch the eclipse. They were extremely patient while we asked several questions. They even help d us at the end to order the additional products we wanted.
