Find a 8.1L engine. Thousands of them available and should bolt right in. More HP and torque with the same poor gas mileage.
If I remember right, the exhaust manifolds on the 7.4 are prone to cracking and replacements, for the RV ENGINE MANIFOLDS, are almost impossible to get.

@2bzy2c, @rgatijnet1
- A different engine, I have thought about a different engine, and I know it will probably be a feasible solution, but I am going to wait to see what my machine shop will tell me over the crank and block. Then again I don't plan on really driving it that much, but ideally, I want to still touch everything. Not sure if that makes any sense, but with this build, I want it to last and to the next person that gets this, probably my son, but I want them to keep it and maybe appreciate it. I know it's won't be worth the $ but the hard work will be priceless, and hopefully pays off.

So day one of the home tear down, and unfortunately, well I knew it was coming and expected it, rust, mold, and freaking bugs everywhere. So now comes the fun part of ripping the sides off, and start to dry it in. Out with the rusted steel, going to be recycled, and in with (probably aluminum) or wood. We will see after the teardown phase. I am not sure I want to keep the fiberglass siding as it has already had cracks and barely touching it in the wrong spots tears it. I am going to be looking for options for siding replacement. This is going to be a complete teardown on the home side, going to salvage most of the interior pieces that can be upgraded at a later date. So this is where I mentioned that the people who built the home part really didn't care too much, as I found that most of the screws were held on by glue, the outer fiberglass, and foamboard. No wonder why the sides came up so easily. I have to go find my impact screwdriver to take the windows out. I did see a very long bolt that went to absolutely nothing, just sat there dangling. The wiring is done, I can tell where it has shorted out behind the fridge, that would be a bad spot for a fire to start.

- The engine is going to car wash to get most of the oil and grime off of it. I will see what machine shop says about the number three-piston, maybe get another connecting rod. I will be ordering my rebuild kit in pieces as I want to pick and choose certain parts. I get to visit my buddy to go see what aviation scraps I might be able to salvage.
- I have not made the decision on if I want to keep the roof ac system or go with a split unit?
- I need ideas on the siding on ideas of materials, for right now I am just going to have a pretty much open concept bay inside and design as I go. The window locations will stay the same, maybe. As far as where the door is located that may move if I can make it possible and safe. I would also like a door in the back as a secondary door.
- Steps or ramp? (the motor on my steps is out and I am planning on doing some type of manual type anyway. I don't want to rely on a motor for getting in and out.
- Another idea for in the distant future does anyone that goes boondocking carry like a solar electric fence to put around the exterior just for security type purpose or anything like a perimeter alarm. The last thing I want to do is to be out in the middle of nowhere and have someone/something come upon me.
- I was looking also into undercoating, which I am probably going away from that stuff as I don't think I will really need it. just going to go through with some rust inhibitor to keep that part down.
- The teardown is going to take a good part of the week, going to be 100+ and humid. If I untarp the thing it will more than likely rain.

Well off to sleep and another bright day tomorrow.

So onward to ripping the sides off, I was going to try and salvage the sides but afterward, I tried to pull most screws and they were rusted and stuck, impact screwdriver was my friend here. Then I started getting into it, and one thing led to another, so I am salvaging the parts like the doors, windows, most interior pieces. But with the smell of mildew, I am not taking the chance. Structurally sound is a big NOGO. I will try and upload the pics later, will be going down to the floor after I rip that roof off (maybe salvageable, which will be a big plus, this is where I will align my studs for the sides along with the bracing to attach cabinets and such. My plan here is to salvage the rocker panels and the front nose where the windshield is, although these parts will get a new coating.

So thoughts while I was ripping this thing down, after looking underneath and seeing how they made it to the 40 ft mark is really disturbing, seems like automotive car wise, there is no standard or rules really on how motorhomes are constructed. If it works for now it's good enough I guess. (going to the drawing board on this one) if anyone has any layout ideas I would like to hear them.) My thoughts are to maybe make the motor home shorter. I do not see in reality how this is supposed to tow anything. I am very surprised that the thing hasn't collapsed. Looking at the wood compared to the steel, wood is going to be my number one option with aluminum being high on the list as far as support. So the passenger side may get a door depending on if I can find one. I am going to install electric mirrors (which seems like I have an abundance of)

While bringing down the AC units, the thought crossed my mind on how a dual-zone ac unit on a car worked compared to a home ac system, compared to how the RV system is set up compared to a split mini-unit. Is there a reason I cannot find a permanent magnet motor for the AC unit? Does the unit really need two separate systems or can I use stacked condensers to run both units off a single overhead unit? But of course, I would need the evaporator inside. Put those units were heavy, I will see if anyone has any ideas on this and research what I am going to be doing.

How much do the foam boards actually suppose to weigh, mine were like almost 20 pounds each section (maybe it still had some water or something in it). Comparing to the alternatives to skin it and seal with some insulation leaving the cavities somewhat open.

So my thoughts right now have come to mind to strip it down all the way and clean it up, alternatively, maybe sell it as a stripped chassis with a rebuilt engine. I am not sure how much someone would be willing to pay for that compared to it previously but for me, I think I would have paid a fair amount, knowing that most works had been done, has a sound engine/trans, and would be ready to customize the back end.
And then my thoughts if I get another one, what would keep it from knowing how it was built and what shortcuts were taken. It's just the comfort and satisfaction of knowing this. Yes, maybe a little more hard work compared to the turnkey and go models and get rid of it when it starts to have problems. But my thought process on this is what it would be worth to me. I know most people don't have the time to put into this.
My wife commented after I tore it down, just put a connex on the back of it??? And there goes my mind thinking once again on if it would it is a feasible thought if any extreme work needed to be done then unbolt lift and proceed. What may be a half-day work to remove the box? You could maybe get two or three different ones depending on what you were about to do. (even lighter would be the haul shipping container things)

So ongoing trying to be nice and easy taking this thing apart, am not sure why seems, I know I am trying to save some of the metal beams but does look like that doesn't want to happen. Keep pushing forward.

Wow. Without pictures I can only imagine what it must look like. You have removed the walls and roof? Best of luck. Looking forward to pictures.


My advice is worth exactly what you paid for it.

Rebuilds like this NEVER make financial sense. You paid $2500 for the coach and when it's all done it will be worth MAYBE $12,000. It's just $$$$ wasted.

We have traveled all over the world and seen sights that many may never see. One two week trip down to Machu Picchu in Peru cost us close to $7000. We never got a cent back on that trip but I would hardly call it $$$$ wasted.
Sometimes you do things just because you can and because it makes you happy. With RVing you always lose money but most think that the investment is more than worth it. As they say, you only go around once..... [emoticon]

Sorry, but a 1990 Southwind motorhome in perfect condition, with low miles and babied would still not be worth $12,000.

Southwind resale value...$2500
Experience...Priceless

Honestly, I wouldn't call it money wasted, my math is $2500 for the coach, granted it was too much, but this is the way my theory is, I fix the thing the way I want and take my own shortcut where I see fit, in the end I will have a coach that will probably outlast some of these 100k newer coaches due to the quality of the build. I have been following post on Facebook and such on some people taking delivery on their BRAND NEW 100K coach and try to get warranty work done due to leaks, holes, and etc...and guess what...that warranty is not really there, throw a bandaid on it or a piece of tape depending on the repair shop and send you out the door. Even reading through the RV Tips page for Texas the manufacturer even admits there is no quality control.

For the build I am working on yes I may not recover what I am putting into this, and yes it will take me a while to get it where I want it, but guess what, if something happens to it that needs to be repaired, I got it. And hey if I want to I can go and upgrade it as time goes on. And if I do a quality build, to me it will be priceless, compared to someone buying a build and hoping that someone slapped the thing together right. To me I rather do it this way.

If you see some of the stuff on this thing that came from manufacture cutting corners to save $, then I would be very wary about how the new ones are built.

Lol, that reminds me of my 1ST showing off his hot rod car, I asked him if he built it, NO, then it isn't worth anything except for what you paid for it.

This is what is under the long cap that runs front to back. If the metal would have been protected it would have been ok.
