due to multiple contacts with kali DOT concerning trailers over the years, I've learned a few bitter lessons. these rules apply to kali, your state may be different.
-bumper pull trailers max at 10k/lbs gross for class C DL's
-fifth wheel/gooseneck trailers max at 15k/lbs gross for class C DL's
-max combined length for truck and trailer is 40 feet long for class C DL's
-CHP/DOT has not been openly enforcing the 40' rule due to the number of bluehairs that are in violation with their RV trailers and they also vote.
-there are rules in place for regulation on RV's and RV trailers governing length, weight, and brakes but enforment is lax at the moment.
-mobile home axles are illegal for use in kali as a trailer axle. if you are caught, your trailer is at risk for impound or worse, a OS tag.
what I have learned over the years in hauling our beloved diesel pickups on a trailer.
-cheap trailers are your worst enemy. homebuilt trailers are at the top of the list.
-you need a 20 ft trailer at minimum, you can bias the load forward or rearward to add or reduce weight on the tongue.
-a 25 ft trailer can handle a crewcab with no issues whatsoever. a 20 ft trailer can get the job done but you have no options on load bias.
-five lug wheel axles are a no-no. six lug wheel axles are the bare minimum for a 10k trailer and you need 2 of them for safety. 8 lug axles are the ideal since there is plenty of load capacity and if you own a SRW truck, you have one less spare tire to carry.
-trailer axles bow downward in the center as they approach load maximum rating.
average weights of ford diesel pickups without a payload are as follows......
-RC trucks are 6k/lbs
-SC trucks are 7k/lbs
-CC trucks are 8k/lbs
of course there will be some ******* challenging these numbers. these are average numbers ONLY, not absolutes. it is only meant so you can estimate the weight you will be hauling. what does this mean?
-the average weight of a 10k trailer without a payload is 3k/lbs.
these thoughts are only divluged to stimulate thought. not look for open arguement. if you want to argue, great. you win.
if you want to take these thoughts and formulate safe load and hauling procedures, you are the real winner.
only you know the terrain, traffic and weather conditions you wil be hauling in, and only you can make the proper judgement and risk assesment. when towing a trailer, the opportunity for things to go wrong badly lurk at every corner.
