I do like the classic lines and color choices of that era Intrigue! And, these were still the golden years of CC quality.
That being said, I did notice that the front slide is the shallow slide, and that deep slide that came in a few years later, rally opens up the front living area. And a personal choice for me, is prefer non slide kitchens. As you have less chance of moving plumbing problems (Though most of the higher end coaches do these very well.), but more so for the lost 6-8" of upper cabinet space for the slide.
Obviously I'm a CC fan
! Prefer the ISL vs ISC, but the ISC should have plenty of power for that 36' coach. (I like Jake Compression Brakes, and that is not available until you get the ISL, and then for sure not in all coaches, as many of them use Exhaust Brakes.). Like the extra HP/Torque of the ISL as a nice 'kicker'
And the Monaco Dynasty, Windsor, Executive, Signature of that era, were well thought of coaches.
This may come down to which coach you find that is within budget, in best documented condition, and meets both of your needs...
