To tow both your SUV and trike - I think the type of dolly Tunes indicated is the way to go... but may still be a challenge staying under your towing weight.
For a single tow - I prefer the 4 down option - and Jeep Wranglers tend to have a long life... (knocking wood) I expect the investment to last a while.
We tried to set up this RV so the wife could handle setup/teardown if needed. If the towbar is already on the rv and crossbar already on the front of Jeep - she should be able to hook it up herself. (Falcon All Terrain towbar that allows hookup and release without perfect alignment and off-level conditions... and Invisibrake that is 'plug and go'.)
I think a tow dolly would be a much bigger challenge for her. I've used them in past - pre RV days...
