X2 That was my thought also. THEN to have nonoperative brakes in the toad pushing you downhill, pushing against you when braking at the same time? Especially being "relatively new" at the wheel of a 40ft DP with a large SUV in tow? Wow!!!
RV safety is dictated by fully operative equipment and a capable operator.......I'm afraid this scenario demonstrated neither.

70 mph while towing will get you a ticket.

True, and 45mph down a curvy steep grade is pretty normal for me and a lot of the commercial trucks out there.

Speed limits dictate the highest speed you are allowed to travel. THE CONDITIONS dictate the safe speed to travel. I'd say her conditions dictated something around 45. Flashers on I hope.

Good for you. As noted by others, the speed limit for vehicles towing is 55 where you were, so 45 on a long downhill is absolutely reasonable, and safe. I'm kind of thinking maybe you should be doing more of the driving, even after your husband's arm heals.

That is a HUGE annoyance I have with my exhaust brake--it triggers the brake lights and they override the flashers. So when I'm going downhill with the exhaust brake, I can't use my flashers and people behind me think I'm just riding my brake and there's no way to signal that I'm going slow.

One set of our double tail/stop/turn lamps flash and one is solid when the engine exhaust brake is applied. Nice feature and maybe only to Thor? Really don't know and have been behind very few coaches going up or down passes, usually trucks.

When I took my truck driving course a few years back they told us to use the 5 over 5 under rule. Chose a safe speed to descend the grade and allow speed to go over by 5kph then use brakes to bring speed to 5kph under chosen speed. This method allows brakes to cool down.

If the hill is straight (just steep), they generally don't change the speed limit for it. It would be nothing for a car to decend it at 70 mph.
If you want to fly down there in your 40,000 lb DP, at 70 mph, be my guest!
I know I won't be!!

Going to be blowing my doors off. At most I would be going 55, which is the posted speed.
Last I heard the fellow overtaking was responsible to do it safely.
If there is a posted minimum everyone is responsible to meet that speed.
I would sooner have someone go down under the speed limit and under control than faster than their comfort level and have a runaway.
Many people forget how they felt when they first started driving. Everything came at you quickly, many things to watch for, etc and you were going less than 30 mph.

I do the same thing and have been driving a MH for many years. This woman was semi new to this. You are not very considerate.

Leo...Agree totally on the braking, but not on the driver. We all started some where, some time including you, so give her a break...Jeez. If anyone is at fault, it's her husband for putting her in that position......but we don't know really. He may have said, honey, let's wait until my arm is better so I can fix the brakes, then we can go....but she said.....

Whatever she said was right, and if he thought otherwise, he,like me, is an idiot. My beautiful half taught me that.

It is not the vehicle going slow(safely) down the hill that causes accidents!! It the impatient guy that wants to 70 that will be the problem!!

Never stop learning about your rig
In the last 2 weeks, I have learned a bit more about up shifting and down shifting. I run a 340 HP DP, at about 32,000 lbs, without toad. While driving through Colorado, the Dakotas and NM, I found that I began downshifting in preparation for the coming uphill grade. I found that if I can keep my rpms in the 22-2600 range, I can maintain my speed with very little loss of fuel efficiency. I spent a lot of time in 4/6th gear.
Back to the original question though, I tend to spend most of my time in 4th gear, going down hill. Most of the grades encountered were 4-7%. As has already been stated, if you are gaining speed in your selected gear, you chose too high a gear. Brake it down and drop another gear. I have a toggle switch that allows me to engage the engine brake at my choosing. Often I leave it in 4th and toggle the engine brake off and on, to maintain the desired speed, and never touch my brakes over a 2-3 mile descent. Nice thing about the toggle switch, it is quite obvious when it is engaged and when it is not. The toad makes some difference, but not much (4000 lb van with surge brakes on the dolly).
