I've spent a LOT of time towing trailers. Started two days after I got my license with dad teaching me on a trailer with a set of 35' long stainless handrails.

Most my tow time now is with a gooseneck horse trailer and we see plenty of accidents on the side of the road. Most of them are related to an under planned setup; usually too little truck or trailer.

Go with the larger frame.

I do know where a tilt trailer is for sale though.
