Yeah I think you have at least 3 strikes against you - towing with a CVT (never do it), towing over the weight limit (trailer plus honda will be way over it), and towing where you'll have some elevation changes.
Subaru Ascent has a CVT with a 5k towing capacity and little to no reported issues on Ascent forum and Allision transmission is developing a CVT for Medium to Heavy duty commercial construction machinery. ZF cPOWER CVT Transmission
So yeah CVT had some issue at 1st, but Subaru, Toyota and Honda have worked out most of the issues over the past 15 years. Plus they are a joy to drive if you don't drive them like a teenager or a car journalist

For everyday normal driving they are great and when towing up hills they put the engine is sweet spot 100% of the time. They as bad as most people make them out to be....but i will stay away from any Nissan CVTs or some of 8 speed RAM transmissions
