1. Reverse your tow car up onto small ramps (you can buy them cheap from a camping store) this will raise the front of the trailer a good 4-6 inches which will lower the beaver end of the trailer 4-6 inches and also lower the pitch of the ramps.
2. Wind down the jockey wheel which will have the same effect as the ramps, but I prefer the ramp solution.
3. Put a block of timber under the end of each ramp so that you drive up onto the timber then up onto the ramp.
4. Buy 9ft ramps (as I previously mentioned a few pages back)
