I’m not retired (yet), but I have a motorhome. It is a cost sink (so definitely not mustachian here) because I cannot use it as much as I’d like (working 100%, I “only” have six weeks of holidays, after all, and we can’t always use it because of other issues like sickness, family constraints, etc.).
But I would still buy it, and I am eagerly waiting for retirement (in 9 years, if I don’t pre-retire) to be able to use it more - or maybe buy another one (depending if children are still coming with us or not)
I could cover this whole topic and am happy to answer any questions, but renting one for a week or two is a good suggestion. Campervans and motorhomes do not provide as much freedom as you might expect.
First, like any vehicle, it requires active maintenance between trips and preparation before you leave (unless you are on the go every weekend and keep everything functional at all times). But still, you need to fill the gas and water tanks, test the fridge, etc.
Second, you have to size them to your needs. We started with a 6-meter-long van (Fiat Ducato fourgon), but soon realized that four people (two adults, two kids, and two dogs) were too many for such a vehicle, especially if you travel in autumn or winter. So we upgraded to a 7m50-long motorhome - it’s fantastic and easier to drive than our last 6-meter van.
Third, you can’t decide to go anywhere and stay there with such a vehicle. So you need to plan your trip (camping or camping aires). Most countries (and Switzerland first) aren’t open to “camping sauvage”, so you can’t just hope to find a place anywhere. And not speaking of the height limits on most beaches in France.
I bought mine in 2020 and think I could resell it above the purchase price. The prices have risen so much that the resell price is often higher than the purchase price.
Consider also the cost of camping (aires are usually cheaper, but sometimes they are just parking with electricity and water—not what I like). I just compared the price of a camping spot in a campsite that we enjoy in Ardèche. It’s almost the same as renting a mobilhome for the same period—only we provide the housing on wheels.
But it is a lifestyle, and settling in one place and having everything ready is nice. Or almost, because you will still have to do some minimum installation once you arrive at your destination (connect electricity if you don’t have solar panels), eventually water and grey waters if the campsite is equipped for that.
But I like that, and so do my kids (and dogs). But that’s a choice; we don’t travel to exotic places with long plane trips.
