Just got home from a cross country trip from Salina, KS to Vancouver, WA (1755 mi). We towed a small U-Haul (4x8') trailer with my model Y. It was fairly easy to hook up the trailer. I had Tesla install the trailer hitch after I bought the car. The Tesla service guy in Vancouver told me the self driving would work on the highway but this is not true. We could only use the cruise control. The car handled well and as everyone else has stated the only draw back is the loss in range. We used the consumption graph and also ABRP (A Better Route Planner) to plan the trip. In ABRP I set the Tesla energy consumption to 500 Wh/mi. We used ABRP in the hotel rooms at night and as a double check to the Tesla's routing. The Tesla quickly adjusted to our new towing range and gave very good estimates of what our range was likely to be. The biggest affect on the range seemed to be wind resistance followed by the steepness of the road. It was the lowest in Kansas where there was a lot of wind and a small but constant uphill. The steep uphills in CO were offset by the downhill regen. We crossed the continental divide at 11000' in the Eisenhower Tunnel. We used the consumption graph on the Tesla screen to show us when we had to slow down to increase range. If our 30 mi average consumption was close to or above 500 Wh/mi we'd slow down. The longest and biggest risk was between Twin Falls and Boise, ID at 127 mi. We charged to 100% in Twin Falls and got to Boise with 20% range going 55 to 60 mph on an 80 mph road. I'm not sure what the trailer weighed--we hauled 2 solid wood heirloom buffets. We charged 22 times and found 3 pull up chargers where we didn't have to unhook the trailer. We unhooked the trailer at the other 19 charging stations. We got only got stuck once in Limon CO but this was because lightning knocked out the power to the charging station. We stayed overnight there but Tesla had the chargers back on line in 4 or 5 hours. I'd recommend getting a CCS charger adapter. We didn't think of this until too late to purchase one ahead of the trip. It wouldn't have helped in Limon where chargers of all types were down but it could have helped in Idaho where the Tesla chargers are further apart.
