obviously your not going as fast as a car, but those who you say at 'trundling' are also likely those going that speed anyway. I'll be at the speed limit the whole time.Most of which is spent trundling.
Sound decent. Furthest I've towed is down to Silverstone. It was one of the wetting F1 races ever and we were very glad for the dry place to sit and drink.Me mate used to take his all over but left it in France, they put it in storage over there and use it for 3 weeks in the summer, obviously can't this year.
We hired a car and drove up from the Costa Brava one year, it's a canny site but I did a week here and there in statics when the kids were young and that was enough for me.
