We could not be happier with our Newmar. We have traveled about 50,000 miles towing a PT Cruiser, cross country twice and into Canada and all up and down the East coast. It is as comfortable as any automobile we have owned, handles easily. We have owned other rvs but Newmar is the best in its price range as far as we are concerned. The structure, design and workmanship cannot be beat.When we are at a campground for any length of time, we often say, this is all we need to live a happy life !!
Even though it is a gas rig ( Chevy Workhorse, 8.1) we had no trouble with the Appalachian,Rocky or Cascade mountain ranges. A little slower going up some awesome roadways, but never a problem, even though we were towing.We averaged between 6.5 and 7.0 MPG.
Don't think you can do much better.

This is the 3rd unit we have purchased from Newmar. So you see we are sold on their quality as well as their service.
We have decide to sell this unit due to health & age.
We have travel all over the US & had very little & small minute problems with all three units Nothing that required us to be stuck anywhere. And the few dealers we have been in contact were excellent.
In our travels we spent about 7 to 8 months on the road touring these United States as well as Canada & Mexico. It certainly was great to have our own stackable Washer & Dryer, no need to spend you day in the laundry room at the camp grounds
We sure are going to miss camping with our many friends we have made while RVing.

I'm the second owner of this RV; The floorplan has the most storage of the gas models. I hate the fact that Newmar put the generator under the rear queen bed, so that the noise reverberates up to the bed. I lifted the bed and put a double layer of rock wool insulation and plan on installing "Fat Mat", which is a sound deadening material. The 400 watt modified sine inverter is virtually useless and will be replaced with a 1000 watt pure sine. Quality of the interior is good and the base oak cabinets are very good. Typical Amish attention to detail. I've met both Matt and Pam Miller of Newmar and they are very nice people and are willing to listen to owner suggestions. I hope that Workhorse comes back to life with the GM Vortec engine as an alternative to the Ford chassis/engine. I'm pleased overall with the coach and I'm always on the lookout to upgrade to a newer year.
