I've towed jeeps behind motor homes for years and years, over 20 years. Why? I'm a total Jeep lover and have been driving and owning jeeps since l was 9 yrs old, that's since 1974
. I've never used any kind of extra brake system and have been up n over the Rockies many times. Here are sum tips in using your brakes. 1) when going up the big mountain don't use your brakes. Your motor home will be working its guts out just trying to pull its self and your tow Jeep up the hill. Using your brakes while trying to pull up a mountain won't help. If you can not maintain 41mph put your 4-way flashers on any time your at 40mph or slower. 2) going down the big mountain shift into a lower gear to use your engine to help hold back. Do not ride your brakes to help control speed. When you need to slow down, and do slow down sooner rather than later, jump on your brakes firmly and get your rig slowed quickly, then get off your brakes as fast as you can. Remember if you slow below 41mph to put on your 4-way blinkers. Stay off your brakes as your motor home starts to pick up speed allowing your brakes to cool. Then when it's time to slow down again, repeat the process. Alway keep your speed under control. Wet/snow/ice roads are a completely different braking use process. Going down the Rockies I never exceed 50mph and brake hard n fast to 35mph. Once speed picks back up to around 50, it's back down to around 35. Keep your brakes cool as best you can. That funny smell you smell is the smell of burning brakes from the vehicles in front of you. Be safe out there, and always keep your eye peeled for any sign that says: "Minimum maintenance road, travel at your own risk." Once you see that sign, it's time to pull over, unhook your Jeep and go explore. Oh and that bit about using your brakes on the uphill side... I was just clowning around.
