Not all RV furnaces draw 6.5 amps. My MH's and my last 5er both draw 9 amps. Don't know the make though.
Yep- Suburban makes models that draw anywhere from 2.8 amps to 11.5 amps- Hydroflame is similar (though they have one that draws 1.8 amps).
The differences are all in the cfm rating of the blower motors (though the new models do use about 1/2 amp less than old ones, due to no klixon blower relay, which drew ~.5 amps).
