I have a 94 no slide and I think they are similar in body style and quite likely some of the systems.
I'm in Manhattan KS and I see you're near Lake of the Ozarks.  Since you've experience with RV's already you should be able to figure most of it out but if you're feeling overwhelmed I may be able to come do a walk around/through with you.
Also don't forget the Newell Factory isn't all that far from you (relatively speaking).  If the coach really hasn't been used much for a few years you will of course want the oil and filters changed, lube job and generator serviced.  I would encourage a check of the suspension, cooling system and brakes before you embark on a long trip to FL and to run and check the systems such as compressed air, leveling, AC's, water heater, etc. to make sure they're working.  Newell can help with all those things but it will cost so the more you feel comfortable doing yourself the better.  Some local shops can do parts of it too but probably not everything.
Make sure the batteries have a good charge and will hold it.  If they're over 5 years old probably budget for new ones.  Same with the tires.  There is no universal hard line for the tires but most folks will replace them when the date codes show they are between 5 and 7 years old.
I would fill the black tank with fresh water and let it sit overnight to see if any leaks develop.  Those sewer valves can dry out and can get the drips overtime, more so without use.  And I would fill the fresh water tank and add some bleach, let it sit overnight as well, and then run lots of water through all your water fixtures if they sat empty quite awhile.
There's much more but those things are a good start.
Yours will probably be a 2 stroke Detroit engine, and most likely has a propane tank.
Good luck!  I'm sure your dad is smiling.

Thank you! We are trying to do most of the work ourselves or have it done locally. Tires are good, just put new ones on last year. Batteries have also been changed out last year. We dumped and flushed the black tan and the fresh tank and did a run through of all of the water valves and drew a diagram noting what each are for. We plan on cleaning things up and clearly labeling them. In the process, we found a crack in the water pump, so we will order a new one from Amazon. Water heater works well and lines going from city water allowed us to test everything inside and we found everything working well. Generator is in excellent working condition and we took her out on the highway last night and she did well, however after running for a bit each time we start her, the check engine light comes on but all gauges seem to reflect all is well and she runs just as she should down the road. We would love for you to come over sometime and take a look. We have been to the factory many times over the years for various upgrades and overhauls, but are trying to be a bit more conservative at this point. We will take it there if we absolutely need to. We are trying to acquire some glass replacements from them but will have them installed here at the lake. 

I have posted a photo of the gauges to see what you think.
