Do you recommend unhitching the dinghy over Monarch Pass?

We did Monarch many times with our formally owned E450 V-10 powered class C towing a Jeep TJ. Supplemental braking on the Jeep, paying attention in keeping RPM up when ascending and using correct transmission gear when descending made the trip possible. We did disconnect once for the trip over and it did make it much easier so, if you have your concerns and have a second driver, unhitch and go for it. Otherwise, if your Class C and towed CRV are up to the task, it is doable and is done by many.
