The route via Burford was my very first test of one of those new satnav things shortly after receiving it one Christmas so no Caravan.I accept that you can get options with most sat navs but unless it allows you to specify routes suitable for the size of your outfit it can lead you astray. That trip down the back streets of Burford might have worked that day, but somewhere else it might have been a disaster.
I don’t let it route me with the caravan in tow. I input my route with the aid of Basecamp software and double check on Google. But saying that we’ve done trips to the Mediterranean, Krakow and other places plus UK and it’s been a masssive aid to navigating distances. At times I would even have the car inbuilt and the Garmin in parallel and took the average. Left lane? Right Lane? No carry straight on 👍
