Hi Dave Sylvia and 'Smudge', welcome to the Practical Caravan forum. I'm glad that you overcame the difficulties with the compatibility and can now use the forum to ask questions, exchange ideas and tips and get advice from fellow caravanners.
You will receive good advice about your towing vehicle if you ask on the Towcars message board where the vehicle experts amongst the forumites tend to look first.
As for the caravan, there are as many different answers about which is the best as there are forum users, because as soon as a person recommends one manufacturer on any caravan forum there will be another member who may have had less than positive experiences with a similar make and they will offer completely different advice.
As far as which manufacturer to choose, have a good look around dealers forecourts in as many different makes as possible to see which layout, how much storage space, worktop area, space and ease of use for the washroom etc; suits your purposes.
It can help if you can print off a sort of matrix list with pro's and con's for each caravan that you look inside, and you can tick them off so that you will be able to compare. Look at the size of the fixed bed, is it comfortable, are the seats at the front good to relax in, is there anywhere to hang your dressing gowns?
Take some time and enjoy the process, we took almost a year to decide on our caravan but we've never regretted our choice because it was an informed decision.
Set your budget, ensure that the weights will add up for you, and if buying a used model insist on evidence of regular services at the scheduled intervals carried out by approved dealers. The overall condition of a used caravan is more important than who built it generally speaking.
