Daryl from Invisihitch:
I have a question I am hoping you can answer. I am planning on buying a 2013 X5 in the next few months and need to tow a larger size boat. The boat is about 4,500-5000 pounds with the trailer. My question is whether there is a difference in load capability between your hitch and the BMW stock hitch? I thought I saw you indicate that your hitch would allow up to 7,700 pounds and the bmw would only allow 6000. Is that really the case?
