I to was switched from GMAC to National General and my premiums went from $741/per year to $1415 upon renewal.This is on a 2010 Bounder Classic 30T. Not what one would consider a high dollar mh. I called yesterday to question why such a substantial increase since I have no claims, drive the MH less than 2000 miles per year and I am carried on their policy as a 'Preferred Plus' Tier. I have the Good Sam discount, Original Owner discount, GMAC Family discount so I wonder what my premium would be without all of these discounts? Their response was'Texas had a rate increase'. No other explanation. Its time to shop around.
