No Jim, Nothing lifted or no monster tires, we do have a few around Oklahoma that way!
I think a combination of a 10-15 yr old trailer, 15" tires and todays Trucks they just don't go together with out doing somthing. As the Dexter axle website stated, with todays tow vehicles you may need to raise the trailer.
Have you seen there over/under kit? Pretty simple, adjustable spring seats that fasten one top, bolt down to the old ones, new U bolts and thats it. About $45 per axle.
Thanks,
Todd
