Newbie - First time towing car dolly - looking for tips

After I first loaded our RAV4 I marked the ramps and used a magic marker to make a line on the ramps, so I could line up the front tire when driving on while leaning out the front window. Made it very easy for me to load it by myself. I had loading and c connecting everything in less than 10 min. I never regretted using the dolly in 5 years. I also had a trailer ball on the back of the RAV so when I unloaded it from the dolly I could tow the dolly to my campsite.
