Without cruise, I'll let the speed creep up going down hill and let it drop a bit going up the hill to avoid using too much fuel. It makes a difference. That said, I sure like when I can take my foot off the pedal and squirm around on a long trip.

I never liked the downshifting on down hills either and this is how I avoid that. Most of the time I set my cruise at 62mph for 2 lane highways, shift to M, and roll along in 5th gear. On interstates I run at 72 in 6th gear.

I'm told, yet to be 100% confirmed, that if you perform the annual maintenance they will warranty the Jayco for life. The paperwork I took said the same thing and I did ask if the maintenance was to be performed only there to which he said "no" as long as you have proof it's been done. Just an FYI.
