Thank you
A 5 star company! We recently purchased a 2014 Forest River Wildwood travel trailer. Being first time owners we had a ton of questions and concerns. We made several trips in trying to make up our minds on what the best fit for us would be. Mike was AWESOME! He was patient and knowledgeable, answering

Gary
great experience
We had a great experience purchasing our new Forest River Wildwood RV from Waterdog RV. The entire staff there was knowledgeable and friendly. We appreciate the no pressure sales experience and will definitely look to Waterdog RV for our next purchase!

Nathan
Great teamwork
Mike helped us find our first travel trailer. We found a great floor plan, Tad executed the paperwork, and Matt performed the PDI and walk-through. Great teamwork and no pressure. Thank you Waterdog!
