You haven't mentioned the size of your proposed tow car. As a beginner it is a good idea to try to tow a maximum gross weight no higher than 85% of your car's kerb weight.
As Rob has mentioned, Eriba's are well built vans, however, they do have a unique styling which does not always suit everyone. The roof elevates and has canvas sides, which can be cold in winter. They also can have limited space above the seats due to the roof and head banging can be a problem. The Dutch love them, but they tend to live outdoors more than we do in the UK.
I would suggest you either try to visit a few shows, or visit as many dealers as you can, before making a choice. Don't pick the first one you see, just in case you have later regrets.
Good luck with what ever you decide.
