Parking my caravan at home

Morning all, I'm new to caravanning and have just purchased a 2 berth Venus 320 a few weeks ago.  Before I purchased I checked the Covenants on my property as well as spoke to the adjoining neighbour to check there would be no issues with parking a caravan on my drive at home.  All was clear as Covenants only covered the first 10 years of the house from new build, plus the adjoining neighbours were fine with it.  I've subsequently had an anonymous letter citing, incorrectly, a covenant on the property. I therefore know I've not done anything wrong as far as that's concerned.  I guess my question relates to whether there is anyone else I should speak to to check whether I am infringing any other bye-laws, etc.  At this stage, I'm thinking it might just be someone with too much time on their hands as the neighbour who could have had an issue is fine with it. Oh well, any advice would be greatly appreciated.  Thanks.
