I'm renting a 2020 Tag XL tomorrow to try before buying. Dealer said I need the distance from ground to top of hitch ball to be 21". My 2015 Outback had a dealer installed 1 1/4 receiver. I'm having problems finding a rise enough to meet the 21". I know folks tow with Outbacks and just wondering what their specific configuration is and where I can buy it. I've checked the towing sections in Lowe's and Home Depot and couldn't find what I thought would work. I'm a complete newbie at this so pardon my misuse of terms, etc. Thanks for any help.
