2-1/2 years ago I bought a 1977 Birchaven w/Cad 500, 6-wheel disk brakes, upgraded instrument panel, 3.70 FD and other upgrades. All work done by the previous owner was excellent and I have no complaints.
I flew from Seattle to Macon, Georgia and drove the GMC back after replacing 2 questionable batteries. I had no problems other than a brake warning light indicating low fluid (HydroBoost). I added fluid and drove on home. I eventually found a slow leak in the brake line near the rear passenger side calipers.
Flying 3,000 miles to drive back in a GMC motorhome you have never seen? What was I thinking??? In my defense I did speak to other GMC people including Jim Bounds so the GMC was not a complete unknown. It was a great road trip with my oldest son (a real mechanic) but I would not recommend it and I would not risk it again. It worked for me but…
There are things I like with this GMC and things I would think twice about.
The Cad 500 – The GMC becomes an even more unique machine with even more concern about finding someone to do major mechanical work. It is a good engine and runs very well but I might not do this again.
The upgraded instrument panel – Very good upgrade.
6-wheel disk brakes – Very effective – Very good upgrade.
3.70 FD - I am old-school. I do not like the sound of higher RPMs. Goes good, though. Goes well with bigger tires.
235/85R16 Tires – Mixed review. I like the look and feel but there is very little clearance. Does lower the engine RPMs which I like.
Quadra Bags – Excellent upgrade.
I am now about to replace the CV Boot (outside passenger side). Parts and tools have been ordered and I have found good information on the internet. Should I also consider replacing the wheel bearings (no known problems)? I have the Warner bearing tool and replaced the bearings on a different GMC 15 years ago. I would appreciate advice and opinions of those with more knowledge and experience.
