Suggestions for older pickup to tow 18k lbs 40'+ FW

Whatever you do, don't cut corners on the safety factor...With wife and children included in the equation, try to match up a truck to tow with that won't cause safety issues even if you only tow once or twice a year...it only takes one time to regret decisions we make in our life. Good luck with whatever choices you make with a 5er and what you're going to tow it with, enjoy and make great memories with the family:)
