I'm hoping someone can help me with a very expensive mistake that I just made. A couple of weeks ago I finally took the plunge to buy a car that could tow a horse float. I sold my cute, reliable and very fuel efficient Barina (which couldn't tow a feather) and bought a Nissan X-trail. My reason for choosing an x-trail was that they are relatively fuel efficient (which is important to me, for cost and environment reasons) but can still tow 2000kg - at least that's what it says in the specs. Well, after I bought it I found out that the maximum towball down load for the x-trail is only 150kg. I've heard that the towball load should be about 10% of the total trailer mass, so that means you can only tow about 1500kg with the x-trail. So, apart from being very annoyed (grrrrrr!) with Nissan and their misleading 2000kg statement, I'm wondering if I can tow a horse float with it at all. I only need to tow 1 horse, but I'm not very keen on single floats (I just read the thread on single floats - some scary stuff in there!). I have access to a couple of different double floats, so I guess I need to find out the towball down load with the horse in the double float - any ideas on how to do that? He's a big solid boy so I'm guessing he would be at least 500 kg, and double float is probably 1000 kg, so it looks like I'm going to be right on the 150 kg towball limit with a double float (10% rule again). Hmmm. Any ideas? Should I just ditch the x-trail and give up on my idea of having a fuel efficient car for towing? I really don't want to drive around in a tank, but maybe its the only way to be safe. If nothing else, perhaps my experience will prevent someone else making the same mistake!
