This is my alu-cab lt50 It's the lightest hard shell roof tent I could find weighing 50kg with the mattress so ideal for smaller vehicles. Having a smaller footprint I haven't really noticed a difference in fuel consumption and I've toured around France and Spain with it. it comes with a rain cover which was an £80 optional extra which I've never used, it allows you to have the rear door open if the weather's bad, it also has bug screens on each door. it's in the same condition as when I bought it, it did arrive with a small dent on the underside which has no affect to the tent itself, I did try to get some money back because of that but the emails ran dry. everything's included to mount it to your roof bars and I can help if you need it.
