I have U.S. Warranties on my motorhome. Problem is they have yet to cover any claims I've submitted. Recently my Freedom 2000 inverter/charger went out and they are telling me it was the result of a power surge. The motorhome was plugged into my 50-amp power share at home. No other problem except the power to my motorhome, brand-new microwave, new flat-screen TV, both ACs, and refrigerator is gone. Should I get a lawyer?
