Not only can YOU do it, getting help is relatively easy. I don't know about other manufacturers, but Tiffin has an extremely helpful line you can call during normal business hours. A good description of what you are seeing, what works, what doesn't work, and especially what you have examined and what you haven't will get you a good handle on where to start and where to go with your home troubleshooting. If you ask, they will also tell you how to get at the part you need to change and what else you need to disassemble to get at the broken piece. Yes, in many cases you may have to open compartments and crawl into basement areas, get under your rig, get on the roof, or wiggle under the dash. Difficult for those of us who are getting stiff, old and yes, fatter than we were at age 20. However, even if it takes us longer to get something done, we can still do it. I'm 77 years old, and have been maintaining my Class A's since I started RV'ing in 2004. Definitely not as fast as I once was, but I still pull wheels, move tires, replace hydraulic lines, and do the many things necessary to keep 3 successive RV's running for over 230,000 total miles. When my efforts find I cannot do a job, such as windshield replacement, 22.5" wheel balancing, replacing a roof air conditioner, etc, I take the rig to the experts, preferably at the Tiffin plant. As part of my preventative maintenance efforts I spend a considerable time under the rig with a good light and a rag. I use a very extensive checklist. I am consistantly looking for chaffing electrical, air, hydraulic or cooling lines, broken or missing zip ties, small seeps that could progress to major leaks and any other tings that just don't look right. Time consuming?? Sure, but it keeps my rig running like new. I don't have systems awaiting maintenance, or deferred maintenance where something hasn't worked for a long time. My current Allegro Bus has just short of 95,000 miles and is in better shape than when it came from TIffin. Take your time, watch closely when experts work on your rig, ask MANY questions, and try to do it yourself. You really can...
