2013 Ford F-150 platinum
I’ve had this truck for about a year and I need to get into something else been a very reliable truck just replaced the blower motor new starter
Fluids done on time every time from me and previous owner the rear axel however is starting to hum will need replaced other than that everything works great 4 wheel works but does make a pretty strong engage if not all the way stopped
