chaplin...dont have an era but have had my spf on a u=haul trailer on a couple of occasions. i raised the front of the trailer using the trailer 'jack' assembly at the hitch area to reduce the angle of the drive on ( while hitched to the tow vehicle) . i had to remove the license plate on the trailer for clearance. i have 3-1/2" clearance underneath the bellhousing which cleared the trailer with no trouble and have just about 5" clearance under the front body
oil cooler scoop area which also did not 'touch'. . just have someone watch as you pull on and if it looks like you will touch, then back it on. trailer worked fine for me and hopefully for you too. good luck with the u-haul and the dmv. bill
