Smallest toy hauler that would still fit a Funco Gen4.

Whole lot of questions that would need to be answered. I know I would want an 80 to 100 gallon tank. A toolbox would be nice as well. Then obviously the fifth wheel hitch. And maybe this makes a difference on what size bed you get to squeeze it all in there.
Most modern long bed trucks can fit a tank in that size range in addition to a fifth wheel hitch. RAM has the largest footprint factory hitch puck system and my friend still fit a 90gal tank/box combo in his. The Ford & GM systems are a smaller layout leaving more room for the tank. KSH in Havasu can also build custom if you wanted to maximize volume.
 
Just drove a new Chevy LT 3500 dually. Not the fanciest with all the bells and whistles but I could absolutely live with that truck. Midway quoted me 68k plus fees and AutoNation said they could match that. So for that price to me with 100,000 mi powertrain warranty and being a Chevy guy it might be hard to beat. I need to go drive a three or four-year-old f-450 and see how I like it. Definitely a big truck that I would not want to be daily driving and trying to park in parking lots on a daily basis.
 
Have the L5P pumps been troublesome? They do not have the CP4 - use a Denso pump IIRC
I've heard of a few. Guess they're not as notorious as the Bosch on the Ford. Happened to a friend's at 80 kmi. He was out of the warranty time period. Cost him a grip to fix.
 
So dumb question. Let's say I was to look at a trailer like this one. https://www.rvusa.com/rv-guide/2016-keystone-carbon-387-toy-hauler-specs-tr25174 13,300 lb dry with a 19,000 lb gross weight rating. That trailer will take a payload of 5,600 lb. More modern trailer that is 8 ft longer than the weekend warrior le3505. And has slides.The new Chevy 4*4 dually 3500 diesel truck has a 7442 pound payload and a rear gross axle weight rating of 7250 lb. The trailer I mentioned above has a 3360 lb pin weight. From what I can find online it looks like the truck is 1,845 lb on the rear tires axle weight unloaded empty. I want to add 100 gallon fuel tank and a toolbox so let's say I add a thousand pounds in the bed. So if I add up 1845 lb for the truck, a thousand pounds for the fuel and toolbox, and 3,360 lb for the pin weight according to the specs of that particular trailer I would be at 6200. So that would be a thousand pounds under the 7,250 lb gross axle weight rating for the rear. Obviously I know it would be easy to add another thousand pounds to the trailer and inside the truck and be right up on top of that 7200 lb loaded max in the back for the axle. Could I realistically safely buy a trailer this big and haul with that truck stock? These numbers are so damn confusing trying to figure out. Bottom line a newer 7 ft or 8 ft longer trailer like this one with slides adds about 3,000 lb total weight and I would say a thousand pounds pin weight compared to the le3505. At least this particular newer trailer has a load rating that I can feel like I could get my 4,100 lb truck in there and stay reasonable on all my weights. As far as filling that fuel tank and all that weight there which would be about 700 lb that would only be going to the dunes with flex fuel for the sand rail. Rest of the time that tank would be empty let's say we drove to Yellowstone or wherever. It is also confusing gross weight rating of the whole rig. That trailer and truck would be let's say roughly 27,000 lb. I believe I'm reading gross vehicle weight ratings around 31,400 for this truck. Seems to me the rear axle weight rating is the critical item to look at.
 
All the added weight will be shared with the front axle. It won't all be on the rear. Assuming you'll put the fuel and tools at the front of the bed.
 
Whatever you get make sure you don't overpay because you're going to go back to a Pusher. You have been in a coach far too long, and the truck and trailer is going to go from great to hate fast.

Yes it will be in the front of the bed. So that thousand pounds will be probably what 3 ft forward of that rear axle transferring some of that weight forward.

Trust me I'm having a hard time going from our nice trade winds moho even being older. Really like that thing. But to go spend a month or two at different places around the country and be able to run around. Truck and toyhauler is the only way to do it that I can see. The rig will do three things for us. Sand dunes, LS fest Vegas and texas, and then of course traveling. For me mostly the western United States I want to see. Not much back East that interests me. As far as the two trailers I'm also thinking about if we end up in a national park somewhere that 43 ft trailer is still a beast compared to the 35 ft weekend warrior. Tough call to haul around an extra 3,000 lb to have some extra space. I just want to make sure I can reasonably do it. I think the Chevy truck would do it but we would be maxed out on weight.

A few of your numbers are off a touch. Unfortunately the spec section on the Chevy website is abysmal for these purposes.

The new Chevy Dually 4x4 will have less than 7442# payload - a crew cab Dmax dually 4x4 weights north of 8000# - possibly closer to 8800# if memory serves and the GVWR is 14,000# so 6k at best, probably closer to 5k net.

The trailer I mentioned above has a 3360 lb pin weight. From what I can find online it looks like the truck is 1,845 lb on the rear tires axle weight unloaded empty.
The rear axle at curb will be more than that, likely a bit above 4k. The Duramax is heavy up front but the 8k ish curb weight is somewhat split evenly due to the wheelbase.

Rear GAWR on the Dually is ~10,400# so you have quite a bit of headroom

The dually truck will have a GCWR of at least 40k with the diesel. As far as carrying capability - truck at 14k GVWR + trailer at 19k GVWR gives you 33k to play with, provided you don't overload the truck rear axle.

EDIT: take a look at the specs in this link - much more in depth than the standard Chevy website, corroborates most of what I pulled from memory above.

Good stuff thank you. Damn they make this difficult.

You're welcome, and if you happen to test drive another truck, the Chevys have a label inside the driver door that lists the vehicle payload and max trailering for that specific variant (model / wheelbase / tires / engine / options / etc).
 
Would have never guessed that truck has 4,000 lb over the rear axle empty.
