38A Cruise control

We're finding that with cruise control engaged, we are losing 5-8 MPH Going up a hill and then gaining that much on the downside of the hill. If we manually downshift or disengage with the pedal, we can maintain speed. Seems as though the cruise does not downshift soon enough up hill to maintain current speed. Doesn't seem like we should gain speed going back down.

Do you have the transmission in economy mode?

Also, what is your speed and how big is this hill?

I usually keep the cruise set but manually down shift if I see a decent hill coming up. Coach maintains speed just fine.

The trick is downshifting early before you start to lose momentum. It's a 33000 lb MH not a 4000 lb car. You need to be proactive. Don't be afraid to down shift. You are only giving the transmission permission to downshift and it won't let you do anything that would hurt the motor or transmission.

When going up-hill, besides watching the speedometer I get on the gas pedal and watch the tachometer. When the rpm's start to fall, I generally downshift manually (using the buttons). At the top of the hill, I hit D (drive). On major down-grades, I touch the brakes when gaining speed to engage the exhaust brakes and the use the brake as needed.

Speaking of exhaust brakes, if I don't have the switch on and I'm at speed, say 65, now I come up on a downhill grade, can I engage the switch at that speed? To save on using brakes.

Yes. No problem engaging the exhaust brake at speed.

To long to list right now ntoesing, but I will share 3 major issues;

- Kitchen sink drain hose behind FP was melted do to contact with back of heater (major leak)
- then found heater itself was not secured in its mounting (that took a day to fix
- major daylight from under kitchen slide (factory has new seal fix for that, but you may already have that seal on the 2016)
