Sold a trailer and now for a new one. Looking for a gooseneck trailer, maybe aluminum trailer, 28-30 ft long and maybe a side dump on the trailer. Also wanting ease of loading mowers with a dove tail ramp system. Also want this trailer to be versatil so if I want to use this as a 5th trailer only, the sides come off and we can load block, haul equipment, etc. To much to ask for??
