Is this a good idea

I Have a 13 f150 with 210,000 just used as a farm truck light came on it’s the timing chain. Cost 3100 to replace. I have other nicer cars for family and work but I need a farm vehicle. I have the option to buy a 09 escalade for 5000, it has new tires, water pump, alternator and battery with 188,000 miles. I only need to tow trailer 4hay and transport large farm dogs. Is it better to buy the Escalade and wait on repairing the truck(or sell) and when money is a little better trade the Escalade in for a new truck or just repair the truck. I only put maybe 1000miles a year and maybe 400 of that is towing hay or a stock trailer all under 6,000#
