Here's my story. I was formerly employed as a transportation director for a company that operated a fleet of toterhomes and trailers. The business was a mobile retail trade that followed off-road motorcycle and ATV circuits such as GNCC. In January 2005, the company took delivery of two new rigs (for a total of five) all similar to this one...
The overall length of this rig is 86', the trailer is 53' In February 2005 (right before I got canned), we had two of these rigs primarily in California, but also running back and forth to Texas. The trucks were never measured nor ticketed despite their 21' excess to the 65' interstate length law.
The problem that I encountered though was the weight of the steering axle. These toterhomes were built on FL120 Century Class chassis with 12,000# steering axles with 6000# tires. The coach builder, United Specialties, shipped these new rigs out to us at 15,600# on the steering axle. Each steering tire was 1800# overweight. Also in February, I drove in a 3-truck convoy from PA to TX. It was an Arkansas scale master that pulled this rig for inspection when he saw the 15,600# steering axle weight.
First he asked for an overweight permit. Second he inspected the tires. No overweight permit--$100 fine + purchase permit $70. Overweight tires--new Load Range J tires installed before truck was allowed to leave the scale for a cost of $1400 for tires and road service. $1600.00 and lost 4 hours.
BTW: The toterhomes are registered with Motorhome tags, but display USDOT numbers on the doors due to pulling commercial trailers. Therefore, drivers are required to have class A CDL and are required to enter scales.
