1980 GMC 7000 4X4 RV project


Recommended Posts

Well I'm going to make it short. Ive always like the idea of going to GLAMIS and not worrying about getting stuck on a RV. So I finally got a rig to work on.  Pick it up from Springtown Texas just before Presidents weekend. I've looked at a few throughout the years and this one had the right price and parts. We where going to buy a new motorhome a few months back in November 2021 For 100k. A C-class gasser new but I couldn't see myself spend that much cash to turn around and get stuck at glamis. What a waste of money that would be to me. So this happened and its going! Here are some pictures. The last picture was from yesterday 3/5/2022. I'm going to continue today.  The goal is to register the darn thing and if that happens then maybe swap the engine for Cummings and stretch it out to about 30-32 ft and add all the accommodations that my current toy hauler has. Solar, slide out etc. I'm going to put my building abilities to a test and see if I can make something as nice as what we where going to buy.

The progress on Saturday and Sunday 3/5-6.

I got $200 for scrap. I think I was 200lbs.  That sucks I'm going to pay alot more for the metal when I buy it.

I jumped the gun and got some threads for it! I didn't think the wheels where going to be that big.

Are gear sets available for those axles?

I will find out soon enough.  The axles are coleman used in farming equipment with Eton lockers. I'm going to say yes they are. And if not then I will go back from 46 to 40's. It was the rims that I really want.

What's really nice about this truck is that it's in between a army LMTV and a regular truck.  So not too heavy but strong enough for a C-class motorhome.

I always wanted one of those big chassis 4x4 trucks. Just missed on a couple of them. I remember they all had really low final drive ratios, like in the 5 to 1 or lower (numerically higher) ring and pinion ratios. 

What engine is in it?

It has a Chevy BB 427 which I'm planning to put EFI on it. The goal is once its registered I'm planning to replace it with  7.3 power stroke or Cummings 5.9. I'm researching with DMV on my options. According to documentation I can use a donor vehicle which is newer than this truck. So anything over 1980. I'm  going keeping the 427 engine for a truggy project incase you guys get any ideas.

Follow button at the bottom of the page I think. So does your truck have a divorced transfer case? A lot of those bigger chassis 4x4s that I've seen do making an engine swap a lot easier because you can stick just about any engine transmission combo in and not have to worry about changing the front and rear drive shafts or the t case

Not too late to setup a go pro with the time lapse feature. Turn years of work into a short video. Could clamp it to the awning support on the trailer as one view. I like watching those videos because you can learn a lot and get inspired for your own projects.

I hope it turns out better than this.

I actually started to record it to post. I got s gopro10 just before I cut most of it off.

Updated.  Got the truck down to the frame. Removed the front bench. Now I'm removing all the excess wires before I connect the batteries on the engine.

Do yourself a favor and call a ref before buying a motor. There are a bunch of other considerations like emissions class. 

I found out the hard way chit’s changed a little:
