Towing uhaul cargo trailer with 26' Class C

I pulled a small covered UHaul from AZ to CO last spring with a 2000 Impala. It was relatively easy. I took a back way to 40 and then through NM to 285, not the expressways so didn't have to have traffic whizzing by at 80 mph. I did go over Wolf Pass, plenty of lanes, just took it slowly. Every brand of moving box I could find was at least $1000 while the trailer was something like $100. No contest even with more expensive gas.
