We have Allied as well. Had them on our TT for several years. Last year when we got the motorhome, called CW Insurance to get a quote. They quoted us through National General initially. Had them quote us through Allied as well and it was half the price of National General. National General pays the highest commissions to GS/CW than any other carrier they represent. Something to ponder as well.
But as someone mentioned, it's going to be different from person to person. There are many factors that go into it. Get a lot of quotes and go with the best that fits you.
