In Texas along with probably a half dozen other states its legal to tripple tow. For those not familiar with tripple towing it's simply having two trailers behind your truck. Most tripple tow laws are similiar: 65' max combined length max trailer length 45' max tow bar length 15' Any trailer over 4500lbs requires brakes Safety chains required on trailers over 3000lb 70 mph max daytime speed for any trailers under 26' 65 mph max nightine speed 27' and up max daytime 60 mph and 55 nightime 5th wheels max daytime 60 mph and nightime 55 mph no matter length Tow vehicle or trailer can be no wider than 8.5' and no higher than 14' Max combined weight is 25,999 class B license required for 26,0000 and above I regularly tow a 45' three car goose neck tripple axle trailer behind a 2005 C/C dually 4wd diesel. Next weekend Im planning on attemting my first tripple tow with my 18' ski boat (total length 20.5') behind a 25' trailer, yea I know Im already starting out illegal by .05 buy I figute if a trooper is gung ho enough to stop and measure that close he'll find something to get me on anyways. I was thinking about putting the boat and trailer on my car hauler but even at the back of the hauler the trailet was very close to 14', I know I'm willing to break the law by length but then worry about height? The reason for this thinking is theirs a couple low bridges on the way to the lake Im going to, one as low as 15', but the height sign is old, and looks a lot older than about two or three repavement jobs. I know I cant back up with this rig, but my real concern is cornering. Anyone ever tripple towed and have a few tricks or tips to share?
