Nick, depends on your use - are you spending all your time in Europe/West Africa or are you heading RTW or heading to SA ?
If you are in a SWB a folder might be better- then it leaves you some roof space - in a LWB then a Maggiolina is worth considering. Or if you fancy doing it properly - and something im looking at for a 110 project.... check out
Get out of the drivers seat, walk into the rear of the vehicle, pop a few catches roof pops up hey presto - dont even have to get wet - yes please !
My opinion on a few different makes, ive kipped in all these makes and spent a full 6 months in a 1.2 Hannibal - I use the Hannibal every week for at least 3 nights all through the winter - including snow and -10 !
For European use the Brownchurch has IMHO the best rain protection for a folding tent and its very sturdy - with galvanised fittings it is built to last.
The Maggiolina is a very good alternative to a folder if you are not too tall - better in the rain than all the others and quick to put up and down, but not as cool as the other folders - the Extreme model is best - make sure it is lined or you will get condensation in Europe.
If you are in Hot climates alot the Hannibal/Ezi Awn/Howling moon are great - though the Hannibal IMO is better made than the others with a better fly and matress - I have one on the 90.
Hope this Helps - if you need any more advice/photos then drop me a line
