Ernie, don't have the 330rlts but have the 33rlds. Just had them put on about 2 months ago, they are mounted just like the pics. Have not had any problem with wind noise, but can tell the differance with the sun beating down on the slide tops, much cooler. The wife and I both think that it was worth the money for them. Take care Ernie
