Do you have a suitable tow vehicle? Preferably diesel, automatic and at least 400Nm (c. 300 lb.ft) peak torque. If not have you factored in the cost of buying one and the extra running costs when not using it as a tug? Cost of fuel when you are towing?
Do you have 'grandfather' rights to C1E and D1E licence classes or will you have to do the training and sit the test?
Have you got a commercial/towing Satnav or access to a proven app? Do NOT rely on in-car or dedicated satnavs or Google Maps on your mobile. There lies narrow roads, tight bends and no way out.
Have you ever towed before? I have towed everything from little 750kg garden trailers to 2700kg car transporter trailers and most things in between.
By far the most irritating and frightening to tow is a big empty 1900kg caravan. You will find cross winds, headwinds and gradients you never knew existed. Don't even think about going through any town.
Towing is unbelievably tedious and hard work over any reasonable distance.
You cannot 'make progress'.
You are limited to 50mph on single carriageways and 60mph on dual carriageways.
You aren't allowed in the outside lane of three lane dual carriageways.
Many non-towing drivers don't know this so you get stuck behind middle lane day-dreamers.
You can rarely overtake on single carriageway roads.
You are stuck playing tag with the HGVs. Not fun at any time and downright scary in the wind and rain.
Where will you store the 'van? Parking it on your drive will attract the opprobrium of all your neighbours and may be banned by covenant, lease or bye-law. Storage and insurance can be high depending where you live. Have you checked?
Have you checked the cost of a reasonable 'van? Cheap they aren't!
Have you checked the cost and availability of 'camp-sites' in places worth visiting?
We used to camp when I was a child and have done so a few times with my own children some years ago. I have borrowed a 'van on two occasions. We worked out that now the children have grown and left home it would be cheaper for us to use B&B's once all the costs were figured in.
I have friends with 'vans.
One uses it at least twice per month as he goes fishing at the same stretch of river. He parks it up in a friendly farmer's field. He stores it back home in another friends farm yard. It's a scruffy damp mouldy old thing but for a few blokes for one or two nights it's fine. No need to take wellies and damp Barbours off before flopping down on the seating. It is better than a cheap tent and a sleeping bag on the groundsheet, so it all makes sense.
I knew another who got all enthused with the idea after a week in a static 'van. Spend several 10's of thousands on suitable replacement cat, 'van, awning and all the gubbins every invented. Lasted two long weekends away, parked the 'van up for a couple of years before admitting it was a big mistake!
For balance I know a family with primary school age children who use it several times a year and the youngsters love it. The mother hates it as it's just another small house to keep clean and she has simply moved the cooking duties from a proper kitchen to a diddy one! They doubt they will keep it once the children reach secondary school age though.
So, pays your money, takes your risk.
Of course to most other road users you will occupy that corner of Hell too extreme even for BMW and Audi drivers.
