Sorry I hate to break the bad news but your Kia only has a tow rating of 1,000 pounds and most pup-up wt. are right at 1,000 pounds or more and thats without anything add like an A/C and other things needed for camping
Emphases on "or more". Mine weighs in at 3770 pounds and the smallest in the former Coleman line was 1,200.
To the OP, sorry but your Kia is really not rated to tow anything in the camping world. I hate to be cold, but you need a new tow vehicle or stick to tents.
Please check the towing limits of your vehicle and always stay within those limits! Read and understand your owners manual and any additional trailering supplements provided to you.
FAILURE TO HEED WARNINGS AND FOLLOW INSTRUCTIONS MAY RESULT IN VEHICLE CRASH, PROPERTY DAMAGE AND PERSONAL INJURY.
One of the most confusing areas for anyone considering a new pop-up is the aspect of "what can I tow?" Before you go any further, get your vehicle owners manual, and determine what your limits are. Easier said than done! As towing capacities of vehicles are based on several factors including the vehicle frame type (unibody or frame), engine, transmission, rear end gear ratio, tires/load range, engine cooling capacity, transmission cooling capacity, alternator capacity as well as several other things. Woe is the camper who went out and purchased a pop-up without reviewing what their tow vehicle weight ratings were. The deal you find on a pop-up can quickly fade when you find out you need a new tow vehicle to move it!
Check with your manufacturer to see if they have a separate towing manual. Many do not include all towing information in the standard manual. It will probably take less than an hour, but with the manual and probably a few trips to the car/truck to read equipment stickers you will be able to determine your real ratings (remember to subtract the passengers weight as was pointed out above).
If you start "shopping" for a pop up please
Do NOT assume the person trying to sell you a pop-up will know the limitations of your vehicle.
Remember what their job is in this situation! And if you are talking to professional RV salesman remember if their lips are moving half truths and lies are probably being said.
