I'm looking to buy my first motorhome shortly, having owned large motorboats in the past, the first step in naturally getting a survey done. 

The problem is, unlike on marine surveys, on every motorhome survey company ive looked at the list of disclaimers of how, responsibility for if they fail to do the job im paying them for in first place, is longer than the list of what they actually supposedly check?

I cant see any value in paying for one of these surveys when i have no idea of the competence or thoroughness and that if they do miss something ,no matter how obvious, i have no come back once ive spent my money and bought the vehicle. 

I dont expect a particularly thorough survey to be done in the first place for the typical £300 stated. 

So my question is, can someone recommend where i can get a proper survey done please? 
I would expect a survey to cost far more than £300 to properly check and test a motorhome and all its systems.
