Do your homework on the truck. Look at the gross vehicle weight rating of the individual trucks you might look at. That truck you mentioned will "pull" the 5er but what is the weight on the rear of the truck when your trailer is loaded and your truck has a full tank of gas, goodies and passengers. I had a 2001, 3/4 ton crew cab, short box, diesel GMC and it pulled the toyhauler I had back then and also the 5er I have now but I was over the GVWR of the truck. I now have a 2011 1 ton dually, long box, crew cab, diesel GMC and I feel much safer pulling the 5er. It is also my daily driver. I don't have problems in parking lots, etc. I retired about the same age as you intend to. Been retired for going on 16 years now. It sounds like you're ready to pull the plug. I hope you and your family have a great time with the trailer and I know your daughter will enjoy camping when she gets used to doing it. Good luck.
