Towing Doubles

[rowekmr]

On my way through the Smokey Mountains I saw a Ford F350 towing a 5th wheel and a Jeep attached to the 5th wheel. I never seen anything other than a semi pull doubles. I wondered how is the braking handle? Also is this legal?
Passing the combination I saw a small bar going across the back of the 5th wheel (in between the beams) and that is what he attached the hitch that was pulling his Jeep with.

A 250 pulling a triple axle toy hauler is a red flag for the DOT LEO's

That's what I was going to suggest, as hijacking other people's threads is considered rude.

Hello Everyone. I'm new to the Forums. This will actually be my first post. I'm from Florida originally and hadn't seen anything other than commercial trucks towing double till I got stationed in Cali a couple years ago. Since then we picked up a 37' 5th wheel toy hauler triple axle and a 15' open tandem axle utility trailer. I'm towing with a 2003 F250 7.3L super cab long bed that's mostly stock (for now).

I've put a lot of work into setting my rig up to safely tow double. I've done a lot of custom electrical work in addition to the physical hitch on the back of the camper.

The truck has two separate brake controllers and I set up a set of relays that are triggered by the OEM trailer wires. I used an aero space style cannon plug to run two sets of 7-way electrical connections between the truck and camper. Also added dedicated side turn signals, a manually switched hot, and a spare 12VDC hot.

Once I set up an account somewhere to host pictures I'll upload a few of my rig and build. If there is a better thread to post more build details on please let me know.

Sounds like a cool build! I'd like to see more details on what all you've done.

Yes me too!!

I think I may have lost a couple mph on the big grade ease of Palm Springs. Also I think I may have lost 1/2 - 1mpg.

How fast are you able to pull that grade east of Palm Springs with that load?

I tow in CA 60 and would end up down to 55 in a couple places but 60 was no problem most of the grade. Trans temp at 167 while pulling the big grades. A few times the fan would kick in but only for a few seconds and it was off. I think the temps were around 85 that day.

35k...That's a load, good to know you have the capacity for more if needed. What kind of mpg's you get on level highway?

From Palm Springs, CA to Scottsdale, AZ and back average hand calc 8.3. CA drove 60 and AZ 65-67. Several grades along the way. So my average without the MC trailer is 9.0 with 7 the low and 10.5 the high. As they say it depends.

Nice setups. Good truck for the job. Many of the toy haulers have so many compromises inside I can see why you would want to do this.

Thanks, I have no use for a TH!
