We go to Co about every 2 to 3 years to celebrate xmas, we stay in the driveway in our TT. We go to Seattle the other years occasionally we stay here at home in AZ. We did this one year in 2006/2007 when Denver got 2 blizzards in a row, went below zero many nights. With the thermostat set at 72 we went through a 30# bottle every 3 days. We traveled and stayed with full fresh water tank and filled it when it got low. We emptied the black and grey into the in house toilets with the sewer pump from Camping World. All worked fantastic and we had our space and the rest of the house had to deal with each other with lines to the bathroom :-).
We travel with chains for truck and TT, that year we got caught on I70 going through Vail, and Eisenhower in a storm that we had to chain up. Not a issue at all, just make sure you have the right chains for both TV and TT (absolutely not cable chains, find the chains with the correct weight rating for your rig). Travel with FW tank full and use your TT heater when you stop for the night, it most likely vents into the tanks at least ours does.
Enjoy your trip!
