Youll be fine just take it easy.

at a high level, the physics of this problem are such that you are braking 4 axles with only two axles of power. if you had functioning trailer brakes, all four axles would have stopping power.

There are three cases to consider.
1. Flat ground - the road friction and engine inertia are the only things offering stopping power besides the brakes.
2. Uphill grade - road friction, brake, and engine drag apply. but the angle of the road actually provides some free deceleration, because gravity wants to pull your car back down the grade.
3. Downhill grade - the gravity component will actually accelerate the car opposite of the intended deceleration, requiring more braking to slow the car.

Now ask yourself about your route. Are you driving through a flat, remote part of the country (e.g. Iowa) where you won’t use your brakes much? If so, you will probably be okay.

if mountains or grades or any kind of stop and go traffic is involved this becomes an extremely dangerous endeavor and you’re likely to get excessive brake fade. you’re overworking your truck’s brakes because of the route and the unbraked loaded trailer axles. and on an old dodge you almost certainly won’t have warning until the brake pedal goes to the floor

>the trailers brakes are non functional
fix them

You’ll be fine I’ve towed for years with shitty trailers with no trailer brakes, only a couple times have I smoked my brakes, you can smell it when they’re getting hot, it only happens on long steep hills, use engine braking and not the brake pedal to let your pads cool off, mind you I only drive manuals

Dude I paid a car hauler like 500 bucks to move mustang 1400 miles.

To be honest, I hate paying people for things but this sounds better than relying on the mechanicals and brakes in a 38 year old Dodge half-ton truck.

You didn't mention anything about the truck's condition, are the brakes great or are they marginal? One of the limiting factors in capacity on older trucks was the braking system right out of the factory. I think if it pulls to one side at all you'd be at serious risk of fishtailing.

The trucks brakes feel ok, it stops straight without any weird noise or anything. The front pads are kinda low so those will get replaced before I go.

It also has a small lift with rear suspension and hitch assemblies beefed up considerably over stock, I suspect it was used quite for towing by its previous owners

Trip is from northern wisconsin down to southwest Texas so no mountains.

Why are you planning on fixing the brakes on the truck but not on the trailer?

>>28931268
Time and I already have the parts on hand

I've flat towed a 3500 pound car without any braking from the towed car just fine. It was a short trip and I used an f350 dooley though. You'll probably be fine if you're driving defensively enough to not need to brake super hard

>>28930907
Anything can tow anything under perfect conditions. It's when shit goes wrong that you better be using the right tool for the job. That 3000lbs you're towing is more than enough to roll it's self and your truck if you need to make an emergency maneuver. It'll be much worse if you hurt and or kill somebody and they find out you didn't have functional brakes.

I doubt that setup will have a decent stopping distance if nothing is broken and you're effectively doubling it by not having all brakes work. You don't even need them to fade to have trouble stopping quickly.
Are you really expecting that you can drive 2600 miles without having to brake sharpy a single time? Because if you have to, you won't be able to pull 0.5g to save your life!
Sure it might work out just fine but it seems dangerously likely that you'll end up either killed or in prision for involuntary manslaughter after ploughing through some car / a group of pedestrians. It won't matter much who made the mistake once cops find out you didn't have working brakes.
Just fix the fucking brakes before the trip. You'd still have to do it after otherwise and it's not worth even a 10% chance of completely ruining your life.
