Obviously on a caravan forum we see comments mainly highlighting problems and faults so if you do decide to browse the archive please bear in mind that the majority of satisfied owners of all makes of caravan never comment on caravan forums.
I seem to remember that you rather admired Sprite caravans by Swift so here's your 'Uncle Jack's' Top Tip for this month
Although Sprites are Swifts entry level range they are very well equipped and popular models. Swift are upgrading their Sprite range for 2012 (the new models will appear in September) and this means that current models which remain on dealers forecourts may be well discounted price wise so that dealers can make room for the new facelifted models.
I know that due to your husbands employment situation you have to be very careful and prudent right now but if a 2010/2011 new but pre facelift model is currently outside your budget the upgrade should mean that there will be some late model trade in's available which will also have to be sold.
Coachman and Lunar are also upgrading next years models so let Google be your friend to source attractive deals from reputable sales outlets.
Don't be scared to use your Bailey for breaks away from it all, the damp shouldn't have too great an effect as long as the caravan is structurally sound so you may as well salvage some enjoyment from the unfortunate situation. If you're worried about keeping clothes in the wardrobe just buy a cheapo nylon campers wardrobe from Argos and stick it in the awning.
If the financial discount from dealers doesn't appear to be too attractive don't give in, try to negotiate free accessories such as an Aquaroll, waste water carrier, awning, motor mover, leisure battery etc., and if you can leave the caravan salesman curled up in a dark corner sobbing my work here is done!
