Honestly, a VCT delete isn't a bad route to go but you will need a tune to compensate for it. You'd lose some power, but the added reliability would be nice. Part of the issue with the VCT is poor oil flow in the heads, so if yours are partially clogged a new kit will still make noise. I find running 0W-20 helps reduce startup rattles as the oil flows out to the phasers much easier.
I looked into a swingout, I may go that route if I rebuild the doors on the topper. Eventually I'd like to do barn style doors and reinforce them enough to hang a jerry can and spare tire off of them. I adapted my heater to a 1lb cylinder fitting. It works great, and you'll run out of water long before you run out of propane.
The muffler is forward of the axle, and the tip comes out in front of the tire. I used a Magnaflow muffler, and interior noise is very modest. Avoid a chambered muffler (Flowmaster, etc)
I have a hitch carrier for my water tanks and toliet currently as well, I didn't want to risk spilling it inside the truck and ruining a trip.. I haven't added a water tank yet, I'm still on the fence as we don't camp THAT often, and sterilizing it/winterizing would become a pain.
Well as I may have mentioned, the oil change place apparently wasn't always doing their job, so yeah, the rocker valleys are kind of nasty.
I was planning on having the heads tanked. However rumor has it the oil passages in these heads are kind of on the tiny side... Is there anything I should be doing / having done to the heads when they are off to insure the oil passages are 100% clear?
I've considered the phaser delete, and it isn't a power issue I am concerned with so much as a concern for passing the emissions test in my county at license renewal time.
For what it's worth, as heavy as this truck is, with the gears it has, It's never left the line like a shuttle launch or anything like that. Mind you, it's blazingly fast compared to the old CJ-7 I had decades ago, but then again, my high school bicycle was barely slower...
The purpose behind the melling pump is of course to insure more oil gets shoved up into and through the heads, and VCT system in specific.
What's really scary is I remember putting 10w-40 in my old International Scout 2. Not a super powerful rig, but it did its job REALLY well...
Just FWIW, my current generator is a Harbor Freight Tailgator and I REALLY dislike the noise it makes. I have considered the Sportsman 1K inverter generator as it is compact, doesn't use a lot of fuel, and is reportedly almost silent at 50'. I am more than willing to use a long extension cord to run the stuff in the truck. Basically I need to maintain the power pack / house batteries to keep 12V power available in the truck bed to run my CPAP, and I need to run the AC when it gets nasty hot. As in this time of year...
