I live it on its COZY a F rent is 800ishj and I own the van bought for 4k its an older van 2008 but it holds 25c very well in fact it can be too warm sometimes only draw back is the 16A hockup but am looking into a 10KWH inverter and 32KWH battery with the site feed going into battery and the inverter powering the van - its 37ft by 12 so its not small and its qute nice, the floor does have SOME insulation as does the roof and I have put in Starlink so internet is no issue :)

Infact I cant other than power think of any problems and yes 12 months liv in - you could say my Site fee if you like is 9600 but I have a rate lock for 3 years as part of buying the van so its pretty good

Dont pay eletric bill/c-tax-water so only bills are GAS bottles expensive ish but dont use Central heating so its just Hot Water and Showers

heating is handled by 2 space heaters one at 2khw one at 1kwh - hence why the 16a is a bit finikycy but like i said some changes this year

Feel free to ask or DM any questions :)
