Just drove 500+ miles with a variable 20 kt. crosswind. No problems driving 65-70mph. 75 would push a lot of air and porpoise wickedly but the truck didn't mind. I think I can fix that with a better tie down strategy. The 10.4 is a keeper and the detail and quality are top notch so far. The camper is estimated to weigh a little less then 3400# dry but hasn't been put on the scale by myself.

MPG outbound unloaded was around 13 at 80 mph. MPG inbound was around 10 at 65 mph.

I am not sure if the sway bar is needed.

The rear tailgate uprights are 59" wide, the width of the 10.4 at the uprights is 57 1/2", with a large radius at the bottom. I figure the camper needs to be elevated 1 1/2" to clear the radius.

Also the in bed 7 way female plug is at a position where the open cap conflicts with the camper and the male portion is up against the camper, there is enough harness to move this receiver plug to a better position using a 2 1/8" or 2 1/4" hole saw.

And be aware the truck bed is not pool table flat.

And last but not least, the COG of the 10.4 not including the bumpers is marked 50" from the front bulkhead. I marked the axle centerline of the GMC 3500 and with the camper loaded the COG is still an easy 2" front of the axle centerline.

I guess not last and not least, I'll add this to this thread since I have gone this far, not about the 9.6 but 10.4 buyers/owners may find it just the same.

I weighed the loaded truck and camper at the Cat scales and didn't see what I was hoping to find.

A 2019 10.4 with honda generator and full drinking water, no gray or black, series 24 battery, full propane, empty fridge, hitch extension to the rear, steps not attached, and a little misc but certainly not filled with living necessities, weighs in the areaa of 4200-4300#.

Truck ( full fuel and driver-7000#) with camper as above weighed 11,200#.

Steer axle unloaded went from 4000# to 3660# loaded with camper.

Rear axle unloaded went from 3000# to 7540# loaded with camper.

So even though the truck drove fine and the springs at the rear still had plenty of travel, the rear srw OEM 18" tires rated at 3525# each are overloaded by at least 500# at the axle, probably more since the fuel tank is left side only.

I was hoping more weight would be on the front axle with the regular cab but it appears with the overhang at the rear weight is transferred to the rear axle.

Sounds familiar. I think I was 4400+/- pretty heavily loaded for 2 weeks of fishing and racing.
Where are you with the rear axle rating? I gained 200# I think on my front axle, with fresh water tank full.
You going to bigger wheels & tires?

FAWR is 5600, RAWR is 6700 door sticker. 10k# GAWR.


The 7,000# total and 4000# front and 3000# rear weights were from a landfill scale so close but not real accurate.

Truck, trailer, or tires. Looking at setting it on a gooseneck trailer at the moment. Everything has +/-.

I have wanted a Bigfoot TC since day one so I follow these threads.I never have been one to weigh my TC's but since there is a certified grain scale a block away,I do from time to time for kicks mostly.

Rear axle weight has my curiosity and yours got me thinking about it.So I unplugged my Lance 9.6 full ready to camp minus beer and pop and down 1/2 a tank on one of the two tanks(maybe 10 gal)..9820 pounds total with 3760 on the front for 6060 on the rear axle..

I am very curious what a 10.4 or 10.6 Bigfoot would put my rear axle at so thanks for sharing your weights with the brand new Bigfoot!

Was curious so went down and looked at a GMC dually, they put the truck camper sticker in the glove box, with the diesel which is heavier and might effect the weight it was still only rated at 3933#. So engineering wise the 10.4 would still be over recommended.
