Cabin heat

This is kind of a repeat.
The a.c. works fine.......however, when I turn the control nob to heat, I get about 20% of the heat that I should. It appears to be very quiet warm when it's not too cold out. The engine heat Guage shows normal. Last Dec. When driving to Florida, my wife ad to wear gloves and put a blanket over her legs. I had it to a Jayco dealer and they "FIXED" it.
of course, that was early in the Fall. Can some one tell me what happens when you turn that nob clockwise to increase the heat

The nearest dealer is 100 miles from here. (20 gal.gas)

What chassis is this?

1999 Fleetwood Southwind 35S (Ford F53 6.8L V10) - Toad 2003 Saturn Vue.

It won't do MACH 2, but I can get a sandwich and take a pee.

^ X2.

Is it an A or C? What chassis is it on?

A few thoughts.
The air dampers are often controlled by vacuum. If there is a leak or a line is broken/disconnected, the dampers will not direct the air flow correctly.
Are you sure the A/C is not running when the heat is running? It will run if called for by that same knob that controls the heat output level. A quick test is to remove the A/C fuse.
Sometimes the heater control valve requires replacement to rectify this problem.

Many people hang a sheet or blanket on a long curtain rod just behind the driver/passenger seats to capture dash heat during winter driving.

I will follow up on your suggestion.
The heat is "fairly" warm but not hot like it should be.
