I just started towing a 91 travel trailer w/ my 02 F250 4X4. The problem is, the back end of the trailer seems to scrape on every dip no matter how small. Anyone out there raised their trailer or even put those little wheels on the back to prevent this?

 

our MH has the wheels on the back, really helps a lot, still loud as can be though when they scrape, LOL

I've seen people put a flip kit on thier trailer. Instead of putting the axle over the springs, put in under the springs. Some trailers have this done, some dont.

 

Is your trailer level when you have it hitched up to your truck? If not, you need more drop on your hitch.

 

First the trailer should be level. Use an adjustable ball mount to do this. If your trailer is level then you may be able to flip the axles. Ie put the axle below the leaf springs instead of on top.
