Found a good source to replace just the steel barb on the washer connection on front cowl. They also carry the complete cowl washer assembly: Replacement Steel Barb Fitting | Mill Supply, Inc. (https://www.millsupply.com/steel-barb-49262.php?p=330078)
At local NAPA, I bought 5 feet of washer hose/tubing to replace the sun degraded hose on our coach. And on wiper blades, NAPA part number 6-2656 26", (or 60-2656) NAPA heavy duty wiper blades is a good replacement for the Trico 67-261 26" Heavy Duty Wiper Blades.
Trico on Amazon: Amazon.com: 2 Wiper Set - Trico 67-261 26" Heavy Duty Wiper Blades Fit... (https://www.amazon.com/gp/product/B071VGHQFS/ref=ox_sc_act_title_2?smid=A3ABX95L4MFPPT&psc=1)
NAPA cross part fit perfectly and about same price as Amazon Trico wipers. My NAPA (small town) had the Napa wipers in stock, but behind counter not on the rack.
I get my blades from Costco, Michelin and I have found them to be the best blades
I have ever used.
