5 star ratingThe guy that runs this place is awesome! Very knowledgeable and thoroughly explains everything. Seems like a very intelligent guy! He really really knows his trailer stuff, and has helped me ID the parts i need on several occasions. Well stocked shop and very reasonable prices, always has the stuff I need when I need it, meaning right away on a moments notice! He even went out of his way and waited for me after closing time on one occasion to allow me to pick up stuff I needed. I'm your customer for life!
