we have a T25 high top, pic below. over the years cost a fair bit more than originally anticipated as the original engine blew so now it has a 2.0L subaru engine in it, and i built an ikea interior inside but for all the costs, expenses and stresses its given us so much joy i wouldn’t give it up for the world. sounds cheesey i know, but with a campervan you either love it or just don’t get it.
if you think you’ll only use it a few weekends a year it’ll probably be too expensive an investment to just sit around most of the year doing nowt. but for us we’ve easily got our moneys worth in the last 4 years. in fact i was staying in it last night in the lakes, decided i was going yesterday morning, rocked up, did a ride, made some food, had a few beers with some music on, closed the curtains, put the bed down and home away from home… no hassle booking b&b’s, putting tents up in the pissing rain, dragging bedding across a wet field from a car, having to follow a set plan. the sense of freedom is fantastic. if staying in random spots/car parks doesn’t float your boat you can always just book into a campsite like you would do with a tent anyway
as for T25’s, well check out http://www.club80-90.co.uk for advice on buying and in general. avoid the smaller diesels, and whatever you do, buy the most solid van you can afford. yes our engine popped after 3 years, but at least i’m not sat every weekend cutting out rust and trying to weld it all back together :)
btw we still have a few tents, which we use for backpacking/bikepacking/festivals where we’ve missed campervan tickets etc but we’ve never bothered with huge family style tents so can’t make a comparison to that style of camping
