Look to buy a new trailer....

i don't know about the aluminum ones but i did use a steel one for a year or so. it was a "texas rollback". it goes like this, park where you want, take straps off hotrod, pull pin in tongue, pull pin on each side between wheels, pull foward slowly until the frame of the trailer stops moving, hotrod tips up like on a giant ramp, get in and back hotrod off, done deal. to load hotrod just do everything in reverse and don't forget to put pins back in to tow.
with your low oil pan or a hotrod that sets really low they are the cats butt. the one i used the drivers side fender came off to enable you to get the hotrods door open which was a nice feature tohav efor alow sitting hotrod.
