You seem to have gone from one extreme to another. A
Bailey Pursuit or Swift Sprite (either of which could be towed with a small car) to a Bailey Cartegena which needs a serious vehicle to tow.
Anyway, I bought a Cartegena last July and am more than pleased with it. The bed, having access both sides, is so much better than the side bed of (for instance) the Barcelona. Being of average height, we don't need to extend the bed at night so maintain the ability to walk round the bottom of the bed. The bathroom is great (although the shower is not so roomy as that on the S1 Barcelona) and I have no complaints about the fit and finish. The only (very) minor gripe is that there is no onboard water tank but I've fitted one myself complete with electronic change over valves so no fiddling under the seats for levers.
