I have a sunset trail 300bh. On the crossroadroads trailers, at least on mine, the spacing between the axles is quite wide. When you drive up on a standard trailer aid, at least with mine, there is so much droop of the second axle the dependent tire may not clear the ground. I think the trailer aid plus with the additional 1 inch of lift would be the way to go.
