No problem. if you need anything else just ask. All the numbers are confusing.
One more piece of advice, dont buy the hitch from an RV Dealer. They will over charge you. Take your truck to a reputable truck accessory place and have the hitch work done. You may also want to think about installing the trailer electrical connector inside the truck bed.

It is very simple plug and play. Just get the kit that matches you truck year, make and model. Easy DIY. The RV dealer will charge you out the ears.
