My heavy haul experience says put 5 th wheel over rear axle but I see a lot moved well back does this not take to much weight off front axle?

Hi Trucker1,

 

In a situation where there is only a recreational 5th wheel trailer being towed, they have at most a 5000lb (and often much smaller) pin weight.  Having the hitch placed rear of the axle lifts very little weight off of the front axle.

 

In this build, a smart car will ultimately be placed behind the sleeper, and the weight distribution of a hitch behind the rear axle is even more important to ensure we don't overload the front axle.

 

Regards,

Makes sense so the more weight added in front of rear axle the farther back the fifth wheel can be? If its to far behind is there any danger of tail wag?

I have seen a number of trucks with a considerable "tail" beyond the rear axle, with the hitch placed quite far back from the axle.  What is nice with these rigs, is the "tail can't wag the dog".  The truck weight on it's own is considerable, and the trailer weight can't out-match the truck for control.  I would welcome any other opinions who might have such a combination.

if the truck was left tandem and hitch was set where when the truck turned it just missed the trailer at the back that you would have enough weight on the steer. we are considering putting a jeep up front in the future. we dont want to single it then not beable to put the jeep up front due to lenght

One issue to keep in mind with the idea of your jeep is the overall length.  Most likely, you will need 13 feet of deck to accommodate the length of the jeep, plus you will need about 5 feet of deck space for the hitch.  Usually, the length of the truck to the back of the cab is about 16 feet. 

 

16 feet plus 18 feet of deck = 34 feet.

 

Most US states and Canadian provinces don't allow rigs over 65 feet.  This is quite a long truck and it might limit the length of trailer you could tow legally. 

 

There are many folk who have regularly pushed this limit without encountering issues, but there are some sharp-eyed highway patrols that are aware of these length limits.
