You have to be so careful what info you give to these people, I offer no extra info, I only answer questions asked now, having not been refused insurance, but have had a stupidly high quote, they ask if there any upgrades, this is nothing to do with the habitation area at all, not solar or refillable gas, they relate to the base vehicle, mainly adding power, you have to bear in mind that these people are likely to be 25-35, and possibly never even seen a MoHo let alone have any clue what is inside one, or what can or cannot be changed, tell them nothing, the other option particularly with a used vehicle is "I don't know, I have not changed anything".
Well good luck lying to them, they'll get you in the long grass of a big claim.
