WE had our first outing with our 77 Royal 26ft unit with 403 CID. This was a shake down to find any problems. We live in southern NM and were going to a campground near Timberon NM. We had a huge climb from Alamogordo NM to Cloudcroft NM, at least a 4000 ft. climb in about 15 miles.
Ok now for our problems along the way. We had not gone too many miles when our fuel pump went out. Since these RVs need fuel we replaced it on the side of the road. My wife was following me with her car for a backup AND A GOOD THING. I found that Auto Zone in Alamogordo had one in stock. This took some time, to get the part and travel up and down the mountian for the part and fix a fuel leak on fuel filter on carburetor. Well got it fixed and we were off again.
Next big thing was we did not have much power to make the climb up the mountian. This is time to let you know I was towing a heavy car trailer with a Polaris RZR. The camping was great, we stayed at the Circle Cross Ranch Campground.
Now that you have a quick synopsis of our first time out camping with our GMC. I could use some advice on getting more power for us out west and in the mountains. I think a popular option is to change gearing from 3.07 to 3.70. , this is an expensive option, but could be the best. I could also change the front tires to a smaller diameter, has anyone done this, I am running 16" wheels.
