I have a 2000 Jeep Wrangler 4.0 V6 ...Towing Cap. is 2000Lbs....

I pull an 18ft Alumaweld Intruder .....Works well. Only a few launches have been a challenge. Mainly due to loose gravel and sea slime. 4WD helps...but not in reverse!!!
Check to Tow rating on your Ranger. I think you will be fine......
