I am new to the forum and just purchased a 2017 RRS HSE. I am making the winter trip to Florida next year and will need a cargo box. I had a Thule system on my Volvo XC90 which cost me $1100. I have been searching the internet for solutions but have not found any. I have not priced the LR rails and cross bars with installation but I am going to do that today. I would then need to add on Thule box $500. This starts to get very pricey but if I may have no other choice. Has anyone had experience with this set up on a late model RRS?
