We returned form Jax. Fla. Passed Sat. and Sun. and had low 20 temps. and our Dutchstar stayed toasty with just dash blowing.The whole coach stayed warm as my Disabled daughter who is in a wheel chair which is locked into the floor at the dine table was fine.I had the thermostat for our furnace set on 69* and it never turned on even with the night driving.We did use it when we stopped to overnite in Peterburg rest area on Rt 95 but it keep us toasty all night no problem.I belive Sun. 5 am: start temps where in low 20ez with 35-45 wind gusts, that was not a fun drive in the wind, temps. where fine.
