I know it would require some downsizing and you'd prolly need a lock up somewhere for werk tools, spares, vehicles etc but a larger sited van would give you much needed space for personal gear and a base to rebuild a client list from. People don't like dealing with a "nomad" but on a residential site your address would be something like "Bear's Cave" Bide-a-wee Lane, Towyn, Conwy which looks "settled" and "reliable". Existing customers would just assume a change of address. It also works out cheaper than paying a tenner a night + hook-up fees, insurance and towing costs.
