Hello all,having read probably too much info about travelling by caravan for a long time i would like to ask if the size of the caravan equates to the direct cost,ie site fees,,ferry travel etc, i am very close to committing to a purchase now and although i have read people posting saying you need a larger van than you think,for comfort,storage etc i am still unsure about size to buy,4 berth,3 berth,even 6 berth , in fact to be honest when i see the awning size for some vans surely that doubles in some cases the living size of any van ?? i think i have read too much and to be honest its doing my head in !( theres not much grey matter to begin with) i think i had a frontal labotomy when i decided to become a builder !! anyway my original point,,,will it cost me more travelling with a 4berth as opposed to a smaller van?? thanks...ian..
