OP, Buy a used dolly and decide what to do when you get the next car.
2014 was the last year to flat tow a CRV. Some cars cannot be dolly towed, check your current CRV and the next car.
Flat tow setup with tow bar, lights and aux brake can be expensive but used equipment and DIY can offset the cost.
We flat towed a 04 CRV for 14 years. Bought the Jeep used fully set up for flat tow, approved by DW. But then DW didn't want it as a daily driver - so bought her a different car... Hence the Jeep was the most expensive flat tow EVER. :(
