We have a Pennine Pullman (2000). We find it great. Nice to sleep off the ground - much warmer and beds are comfortable. Only take about 15 mins to set up (without awning). Awning takes about another 20-30 mins I think. We would only put up awning for anything over a weekend.
When we go away for our long holiday I put the sleeping bags and pillows on the beds and fold them up in the camper which saves space in the car, plus the beds are ready for any overnight stops.
We have just taken out the wardrobe in ours this summer, having had the Pullman for 5 years. We found it much better as you can crawl through and put the fridge on before you set out on your journey plus we seemed to have much more room inside. The only thing I missed was the light and mirror that was on the wardrobe, but the light was easily replaced and I'm still looking for a mirror to hang from a pole.
There's loads of storage room under the seats and in the cupboards.
I love the fact that we can sit around the table sitting on the "settee" seats and that the beds are permanently up. If it's hot you can take the table outside and eat around it there.
Ideally, I would like a caravan, but I have to be logical and think that that is only because it would be a bit easier to pack before we go away, although taking out the wardrobe has almost fixed that problem. A Pullman is much smaller to store than a caravan and an absolute doddle to tow. We've towed it to Lake Geneva, South France and the Rhone-Alps for the last three summers. DH and I shared the towing and I'm sure that any overnight stops we had would have taken us less time to set up than any trailer tent.
In short, I highly recommend ours and we all love our holidays in it. We couldn't afford to go abroad any other way (DH wouldn't countenance a tent under any circumstances.)
