Here are the tow weights for our 2006 Jeep Liberty diesel with our
2007 Sunline T-1950. Hitch is a Hensley Arrow. Black, grey, and fresh water tanks about 3/4 full. Tank and 1/2 of propane. Jeep fuel tank about 10 gallons. Yamaha 2400 generator in back of Jeep. Two passengers. Full load of food, etc.
Weights were taken on an Oregon DOT highway scale using the 3 step procedure of Ron Gratz at
http://www.rv.net/forum/index.cfm/fu....cfm#21781221:
Weighing #1 -- TT attached and Weight Distribution Activated
Let Front Axle Load be "FA1" =2450
Let Rear Axle Load be "RA1" =3100
Let TT Axles Load be "TT1" =4500
Then, while in same position on scales, take
Weighing #2 -- TT attached and Weight Distribution Not Activated
Let Front Axle Load be "FA2" =2350
Let Rear Axle Load be "RA2" =3250
Let TT Axles Load be "TT2" = 4450
Then, drive off scales and drop TT. Return to scales and take
Weighing #3 -- TV only -- TT Not Attached
Let Front Axle Load be "FA3" =2650
Let Rear Axle Load be "RA3" =2300
From the above values, you can calculate:
TV weight = FA3 + RA3 =4950
Gross Combined Weight = (FA1 + RA1 + TT1) = 2450+3100+4500 = 10,050
{should also be equal to (FA2 + RA2 + TT2) if scale weights are correct}
TT Weight = Gross Combined Weight - TV Weight = 10,050 -4950 = 5100
Tongue Weight = (FA2 + RA2) - (FA3 + RA3) = (2350+3250) - (2650+2300) = 650
Load Transferred to TT Axles
when WD System in Activated = TT1 - TT2 =4500 -4450 =50
GCVW of the Jeep is 10,100 so the combo is very close to exceeding this value. Axle weight limits for the Jeep are not exceeded.
Considering that the export version of the Liberty diesel, which is called the Cherokee in Europe, has a tongue weight rating of 740# and a tow weight rating of 7400#, and has the same hitch receiver as the US version, this combination seems to be OK for weight.
The combination certainly handles well, probably in large part due to the Hensley hitch.
