Maybe try a campsite next time, instead of sleeping in your vehicle on the public highway. Or maybe wild camping in a remote spot.
Either way, why spend upwards of £40000 on a camping vehicle and then park in the road with the doggers to save £20 campsite fees.............some are open even at this time of year.
We have had a Motorhome since we retired, eleven years ago (well, we are actually on our fourth now).
I have found that there are four subjects which always cause heated "debate" among the Motorhoming/Caravanning Fraternity:
1. The merits or otherwise of using campsites/Aires/wild camping
2. The merits or otherwise of taking a short ferry crossing and more driving vs long ferry crossing and less driving
3. If watching TV is an acceptable pastime, whilst "camping"
4. If it is acceptable to "go online" whilst camping, and, how this should be done (ie "free" wifi, site wifi, MiFi etc)
No one seems to be able to understand that we are all different (even if we own/use a Motorhome/Caravan), and that doing it your way, and, leaving others to do it their way is a perfectly acceptable way to be. IMHO
