I have an Thor ACE 27.1. Bought wipers at suggestion of a truck driver to get extras just in case.so I got one at Camping World and one at Costco (28 in)mine are 29+. So finally went to put them on and the J hook on the wiper arm of my MH is wider. It's been at least a couple years since I got them so no return but where oh where to get replacements?
I saw some on line places but there is no designation that they are for wider arms and do not want to put more money into useless wipers. Just thought they were universal!
