We went in with our must have list and had 2 salesmen and the service manager all working to find a trailer that worked for us.they couldn’t find one on the lot and the salesman Eric remembered a new unit they had on order for stock. It met all items on our list but 1. It had many more features that out weighed our 1. They worked within our budget and we are thrilled with our purchase and the service we got from everyone.

The Poulsbo team has worked well with us in determining our needs and providing the right solution. We have enjoyed meeting folks from sales, finance and maintenance. Extra care has been demonstrated in arranging for special vehicles to assist in placement of our trailer in a rural setting with challenging topography. We appreciate the thorough and thoughtful approach to our special needs.

Our Poulsbo RV sales person was excellent (Nick). He was knowledgeable, listened to our wants and needs, and showed us several RVs before we chose the one that fit us best. It was very low pressure which was much appreciated. I give them 5 stars. Also Colby, the finance man was very efficient and pleasant.

Came here to look around and buy an RV, I was at a couple RV Dealer lots the beginning of Sept and didn’t really like anything I was looking at until I came to Poulsbo RV and was greeted by Matt. Matt was amazing! He’s very informative! He’s very funny and friendly! Taught me a lot that I didn’t know and was thoughtful about my safety! They were able to work with me during a family emergency Into getting my amazing RV that I will be enjoying this fall! Already got my route mapped out! Thank You Matt, Colby, Steven (our initiation RV mechanic) and Nick! Y’all were great! I recommend Poulsbo RV!

I have had a great experience with Poulsbo RV. The sales and service teams have both been very professional and helpful. They worked really well with my pre-sale inspector, and then quickly turned around all the items in the list. As a first-time RV buyer, I would definitely recommend Poulsbo RV.
