All well and good but TBH, is it really worth it?
And my answer would be NO.
How often are you going to get away in it? Can you afford to with current fuel prices?
Also, bear in mind all that additional weight you're lugging around (chipboard isn't the lightest of materials).
Although the idea of a motorised caravan is sound, in principle I rarely see them out and about due to the poorer fuel economy, they tend to sit on driveways, do a few miles then sit in a campsite...
I have been away for odd weeks/weekends camping & have simply chucked my pop-up tent, sleeping bag & air bed in the back.
If I were more serious about using a caravan for camping then I'd look to hire one as close to the campsite as possible to cut down on excessive fuel costs - and not having something sat outside my house day in, day out depreciating in value.
