Hello everyone.I am ready to purchase an X5 ,but I need some real world advice on the six vs the v8 in regards to towing.I did a search,but didn't really find what I was looking for.I have been driving a 1 ton turbo diesel 4x4 truck pulling loads up to 15,000 lbs. for the last 10 years. Long story short,I am down sizing and will only be pulling right at the tow capacity of 6k.The problem is the mfg lists both motors at the same tow capacity,so I am looking for real world experiences on the six vs the V8 pulling 6000 lbs.Thanks
