You live in Wash state as I do and Les Schwab in Sequim is where me and my buddy got our Geostar G574 14 ply G rated 110P.S.I Tires when I had my 2012 Monty and then When I bought my 2015 I had my dealer transfer them to replace the crap Trailer Kings and we have been running them four 4 years now and thousands of miles and love them and they are WAY less expensive than GY614 and just as good IMO AND they gave me 80 bucks a tire for my GY Marathons for a trade in my total bill came to 750 bucks
