We have a test of the Sterling Elite Explorer and the Lunar Delta TI in the July issue of the mag. I've seen both caravans, in depth and the the things you must pay attention to are a) size of lounge and b) size of bed.
The Sterling (and therefore the identical Swift) have quite small front lounges, but the Lunar has a very short bed. In fact the Swift / Sterling doesn't have a massive bed either, but it is better than the Lunar one.
Have a proper lay on the bed and stretch out in the lounge to make sure you can get comfortable. Otherwise, a very nice van!
