One of the interesting things I have been seeing on some of the new trailers is the GVRW more than the combined weight that the axles can carry.Is this something that has changed so that now some of the pinweight is considered into the GVRW?21k trailer with 6k axles,really?We stress these trailers enough without having to worry about this.And a 21k TH, man that is heavy,and pull with a SRW?I switched from a SRW to a DW just because of running downhill from Flagstaff and the trailer starts pushing the rear of the truck around.I drive very conservatively and it was way tooo scarry,and I am at 16k.Please look at total package of TH,weight,length,garage length needed and make sure you will feel good about carrying the family safely.I had to upgrade my TV, hopefully you can find a TH that you will not have to.
