I decided to get these for my 2012 because it would be easier for my 85 YO mom to crawl in and for me to put stuff in the skybox. However, Range Rover said they're only for the pure and prestige models. Not sure why. Has anyone found a pair for the Dynamic? If RR doesn't make them then I'm wondering if I do find after markets, it requires drilling (where RRs for the other models don't since they come with holes for them already.) If so then I might just pass. Thanks.
