Good for you. Make "farmer" turns (get the tow vehicle out in the intersection before you make tight right turns). Your entire rig is probably twice the length of your ride not towing. No tractor trailer but the handling precautions apply as curbs and the edges of culverts are hard on tires
and road signage is not intended as a paint
First time towing avoid pulling "into" any situation that you can't pull thru. You can learn to back later in calmer waters so to speak.
Check the security of your hitch, operation of running, brake and signal lights
, condition of tires
and temperature of hubs more rather than less frequently and certainly the hitch, trailer connector and lights
after every overnite stop and a quick check after brief fuel and food stops can't hurt.
Please take another competent adult driver with you if possible. If this person has some experience towing, so much the better. If not, you still have a potential relief driver, another pair of eyes and hands, an extra cellphone.
If you have extension mirrors or the seller gives you a pair with the trailer, install them and adjust them. Don't tow blind!
