Hi Rocky. Welcome to the RV Forum and congratulations on your first coach and your first Tiffin.
My first coach was a 1983 Tiffin Allegro 29 foot Class A. It was a great coach and we had many great trips in it. My second and current coach is a 1998 Tiffin Allegro 26 foot Class A. When I'm ready for my third coach, I will most certainly look Tiffin again. They are well made coaches and, as Gary said, are backed by Tiffin's well-known factory service.
A couple of things to check out would be the tires, belts, hoses, batteries and any other things that deteriorate over time. Make sure the tires are not older than 5-7 years even if they look good and have good tread. Tires must be replaced at that age because they will fail due to age, not condition. Check the date code on the tires to confirm how old they are. Check in our library for how to read the date codes on the tires. Also replace the belts and hoses if that has not been done. I had to stop on my way to Florida once and replace a fan belt out on the road in the summer. It was not fun.
Both of my Allegro coaches were built on the Chevy P-30 chassis with a 454 engine. That engine tends to crack exaust manifolds from the heat. You can tell if it is cracked by hearing a ticking sound when the engine is ideling. The P-30 chassis is also known for wearing out the bell cranks on the front suspension. If yours are worn, it will wander pretty bad and you will have to fight the steering the whole time you are driving. Those can be replaced with much better SuperSteer Bell Cranks from Henderson's at
http://www.hendersonslineup.com/uncategorized/supersteer-bell-cranks/. Also check the air bags that are inside the front coil springs. The original equipment air bags were rubber and tend to crack with age and heat. If they will not hold air, I would replace them. It will keep the coach from "rolling" from side to side as bad and improve the ride as well. I replaced mine myself for about $100.
There are many experts here who know a lot more than I do that can, and will, help you with questions, problems and suggestions. Good luck and happy trails.
