We have a Hymer 545DB - fixed double bed, and it is super! The construction means that the walls are the equivalent of a 17" brick wall, and coupled with full blown air central heating gas or electric or combined and on-board hot and cold water tanks meant that we enjoyed some great winter holidays.
Of course everyone thinks that their own choice is best, but for us Hymer has been a dream. Plus points include carpeting that is easy to remove and clean leaving a laminate floor that was excellent for holidays in hot weather. Three burner hob and compact oven with rotisserie and grill - why do British manufacturers still insist on full size cookers? Brilliant build quality - check out windows and Heiki roof light. We spent six weeks in France last year, and intend to do the same again. Would we buy another - most definitely yes, but as Lowdham have insisted that Hymer move to the full size cooker, and put the door on the "right side" for the UK we are looking at buying from Germany as we spend more time abroad than in the UK - and the price is cheaper!
This is the Hymer website, click on the Union flag for British spec and one of the others to see continental spec.
