Can anyone recommend a campervan which might work for sleeping 3 (2 adults and a toddler) for a few nights away and as an everyday vehicle? And isn't too expensive for a second-hand good condition one?
I've had a look at various websites and in addition to VWs, the Mazda Bongo seems like a possibility, but I don't know what else might be out there.
We have a Bongo. I have written loads about it here Do have a look. We use it with two adults and two kids. We have had it fully converted but if you aren't especially attached to the idea of a fridge or hob it is a great option unconverted too. They are very useable as everyday vehicles in terms of size, manoeverability etc. However, you might want to consider carefully the engine you go for, as ours (the V6) consumes petrol at a frightening rate. Smaller engine petrol is better though you get less power for those steep hills you always find in the most beautiful places. Diesel is the best option in terms of power and economy. As with all campervans condition is very important, don't get sucked in by a super cheap one and then find you've bought a rust bucket!
I have a T5, I love it. It has a roof bed that sleeps one adult/2 kids, and you can also get child beds that fits in the cab. It has a pop up roof rather than a high top so fits under car park barriers etc, and fits into a normal car parking space so is good to use day to day.
I think weegiemum has a good point about older vans - ours is 25 years old and does need a good emergency fund to keep her on the road and a certain amount of upkeep mechanically. And older vans drink petrol like there's no tomorrow.
I would absolutely recommend viewing before buying and if you do go for an older van take someone with you that knows a bit about them so you can spot any obvious problems. It's often said that body work is the most important thing to look at closely and photos won't always show the right areas to look for dreaded rot in older vans.
If you've never been in one or spent a night I would also either borrow or hire one for a weekend or spend a good deal of time looking around - vans come with lots of different interiors and not every one suits everybody. But interiors can be changed if you're up for a project! We have a high top which is good for storage but doesn't fit under height barriers very easily.
Saying that we've had a really good year (despite having the AA out a few times) and done about 3000 miles in ours. Would we be without it? Absolutely not
