I have been caravaning with the dogs round the shows for 18 years and it is great, you meet up with all your breed friends and talk dogs late into the night, no early morning trapped in traffic jams to get into the show, no 5 a.m. starts, just a quick wander over the night befor to sus out the benching and rings, sometimes get good buys from the stall holders that are setting up the day before.
If you are definately getting a caravan join either the caravan club or the caravan and camping club, and they will do a match for you free, £27.00 if you join with yearly direct debit, and you get reductions on you site fees, the £27 can usually be recouped in 1 trip because of the reduced site rate, and they will help with technical details ,if you use there sites instead of the showground sites that mostly have basic water points and cabin toilets. But there are a lot of good cheap sites in the surrounding area's around show that have the full works, laundry showers and some dog walks, It is well worth it cheaper caravan insurance, use of CL's sites 5 caravan's only great for dogs as not a lot to bark at.
Would recommend getting on with casette toilet built in, easier cleaning, and no trecking across field to find the tiolets at 3 a.m. But I would highly recommend caranvaning, it is my second love after my dogs.
Have a look on auto trader site, there are some good one usually on there at resonable prices, but do the HPI and chris checks ( security)
