I had new 5ht wheel toyhauler with 21 feet of space but the max payload for the garage was 2,500 lbs. I broke the frame on my first trip hauling a 2,000 lb sand car. Spent the next few months fighting with the trailer manufacture and the frame manufacturer. Good luck finding one that will reliably haul a 5k pound Tacoma. 99% of them will have a Lippert frame under them. Google "broken Lippert frame".there are some huge toy hauler 5th wheels that can take full size vehicles
