As the man from the insurance who investigated accidents, the simple fact is that I have not seen an accident cased by snaking on any combination with a good towing ratio although I do accept this is possible. On that basis assuming you are sticking with the tow car you need a lighter caravan than 1500 kg, I would certainly not consider one over 1,400 kg for peace of mind.
Well, I see this as a downside, but as other wrote - an 85% ratio is just a guide. I wish I had a course, but nowadays youtube will give me almost a similar experience (please don't shout at me - I have lot of good experience with learning on YT). My first towing will be on good roads, probably Sunday, so I will have low traffic (I presume).
Snaking is in fact rare and the principle causes are excessive speed and unsuitable combinations although bad loading can be a contributing factor. If you are a careful driver and prepare well you should be safe but if you do find the outfit swaying a bit ease off a bit.
I doubt you will get a bad snake at 50, except in winds so strong you should not have been out in the first place.
Right, and this is quite reassuring - all factors depend on me, and I know how strict I am regarding road safety. Thank you.
I got some reassurance from this thread - from experience people - that I am responsible for the safety, and, as I know myself, I will do my lesson.
So, in summary:
- weight on towbar close to caravan limit
- max 50 or 56 if following HGV (maybe not first few tows) - wont go below 50 on motorway as I don't want to be overtaken by every HGV
- exaggerate every maneuver + watch the wheels in external mirrors
- no pressure in case I need to take a lot of space - I will just block traffic and wait until I am safe to go
- well ballasted (heavy stuff under axle)
- no towing on crosswind > 18 knots
- watch watch watch your speed downhill
- foot off the accelerator when caravan starts to swing
- buy P sign
Did I missed something?
