It will sort itself out in a few years and there will be people who will complain about whatever decisions get made in the way of compromise or non compromise.
Of course the insurance companies will profit no matter what those decisions are but for now they make a convenient flag to wave in the wind storm.
In the long run I just hope that the need for safe and affordable, permanent small housing gets more improvement and the minimum sized of dwelling space decreases from the current standard. A single individual really does not need 500 square feet or more to live a safe and healthy lifestyle.
But a vehicle moving on the road has the expectation of meeting certain standards for safety if they want to tow it around without a special permit and an escort in front of and behind them.
I will continue to sit on the fence and relate to both points of view as both sides have some good valid points in their arguments.
One thing you are not hearing about is the topic of R value and energy conservation. Many of the RVs are not suitable as year around dwellings due to the lack of decent insulation. There are very few areas in the USA where there is little to no need for insulation. Until that R value insulation issue gets resolved there will be little movement available for them to qualify as long term residences given the current energy conservation standards for residential housing. But the RV industry is not concerned about having them be long term residences so there will be no change in that group. There are simply two divergent goals from two divergent groups and that makes compromise unlikely. But who is to say there is not room for a new thing that is neither fish nor fowl?
