Thanks for all the replies much appreciated.
At first I thought having the drop down bed would give more living space but not not sure how much this should affect my decision for example the Hobby in the link below seems to be a nice option and a fixed bed does appeal to me.
I’ll definitely be buying from a dealer as hopefully I’ll get something for my caravan. There’s only so much you can do online so when things get back to normal I’ll go round a few dealers. I agree with the advice given here it’s only when you go around looking you pick up information almost without realising.
