My parents bought one as a retirement project. They’d hired overseas a few times, and bought an older, smaller one, which they kept for a couple of years. They used it, and liked it, a lot, so progressed to a larger, newer, posher one.
They spent many an evening working out their ideal layout, etc! It had to have a fixed double bed at the back, so there was no making up/taking down the bed; a toilet & shower (for middle of the night wees, and wild camping); a heating/air con system; not have to climb up above the drivers cab for bed; and have good storage for outdoor furniture, bikes, etc. They found a 4 year old one which met their requirements, and traded in. They went to a well-known dealer with a big range, so there was a warranty, etc, on an expensive purchase. My dad’s handy, and good with mechanics, so does running maintenance himself.
They use it for two big (6 week) holidays a year - usually one in the uk, and one in mainland Europe. Then there’s at least a dozen weekends. I, and my siblings, are all insured on it, and have used it with families/friends. I’m taking it away in a couple of weeks, so i can stay with a couple of mates, after a wedding, without paying £150 a room in a fancy hotel! We’re in Scotland, so can take advantage of some of the wild camping laws.
We always used to camp in tents as kids, so were always used to that type of holiday too. Love it! It’s a big investment, but because we all use it, it’s worth it.
