1500lbs of solar on fifth wheel roof?

That’s not a lot of energy
Each rooftop AC pulls 1800w. With piss poor construction when it’s 85+ outside they run 4-6hours no problem
Then there’s the typical kitchen appliances.
Couple that with plat panels, on an rv, so exposure will not be ideal (not simply the flat panels, but who parks their RV in full sun?)

Yea it's less than I thought .

It’s more than selfish..it’s insane ..even if they are running a Goodyear endurance tire it maxes out at about 85ish mph top speed..if the are are running cheap “ China bomb” as we call em, they are rated for lower speed ….they can just explode when they build up heat from to high of a speed..

you can picture the aftermath for the rv and the 350 ….and any unlucky innocent driver near them…
 
I've learned when on shore to kick on 3-4 ACs and bring the temps nice and cold before we leave then adjust the thermostats so 1 will kick on when it gets warm then another when warmer than 3rd when even warmer.

I do a lot of day trips and leave dogs in the coach so typically 1 AC will be left on constantly and the temps will still rise a few degrees throughout the day. I only have half the windows with curtains (switching to motorized and wife can't pickout which design she likes best) which makes a huge difference. I'm also attempting to install solar tint on the windows but failed twice so its a work in progress. I have 1800w solar and make 1500w but have about 2000w total load with AC and other devices running.

Found that running the 1 ac on my 12V Victron inverter then set it to pull 13.5A from my 48V victron inverter it'll drain the batteries on my 10kw 12V system and the 10kw 48V system the same since the 48V is getting the solar. Gives me about all day then we'll pull in home with a low charge.
If not enough battery I'll wait for it to get warm and kick on the genny and turn on 4 ACs to drop the temp and pickup a bit of charge. If i wasn't having alternator issues it would be much better but winters coming and now gotta figure out the cold weather planning.
I would have installed a split unit on the camper if you want to run on solar.

Fortunately, I don't see too many RV's going that fast. We have toll roads here with speed limits of 85mph.. and I'll be darned if the stupid semis don't try to reach/exceed that.

Solar just goes over the ACs and just needed to be a bit angled as they're attached to the awnings which are a bit shorter than these tall AC units. The oem dometic penguins were much shorter so could have been flat. The angle really seems to help with solar and keeping clean too. They're sized differently too, upgraded 4 of them and have 1 new one in the box just waiting to get new #6 and install soft starts on them all so then I can finish rest of solar. Swapping 100w panels with 320w I think then having one in the front angled to help with wind.

Yea that's the point , I don't care if they kill themselves , ( crack on for all I care) .

the collateral damage is the real issue
Many years back, I was almost killed (or at least seriously injured) from a giant piece of retreaded tired that flew off a semi.. I was 4 or 5 cars (other actual cars, not car lengths) behind a semi whose tire came apart almost in one entire piece and it flew through the air and smashed my windshield and the entire top of my car down to nearly the steering wheel. Fortunately, I saw it coming and ducked (but couldn't steer out of the way in time). The semi just blissfully drove away.. I had to get another car.

I took the thing home with me, it weighed nearly 100lbs.
 
I didn't see any questions/comments on axle capacity and tire load ratings. If you plan to stay put in one place, you're probably ok - except for the center of gravity concerns getting to the place where it'll sit for the next ten years.

When all is said and done, moving it from point A to point B has two forgone conclusions, possibly three:

1. Center of gravity - you roll it and there's goes your 7200w investment.
2. You break an axle, you roll it and there's goes your 7200w investment.
3. You blow a tire, it swerves, you over correct and you roll it - there's goes your 7200w investment.

Instead of being the coolest kid in the campground, go for what works and meets your needs.

Common sense assumes OP has the weight capacity for everything including tires BEFORE considering this at all. Although common sense isn't so common anymore

I don’t see many either.. it may be because they don’t last long…but that’s humans doing their thing…

Was at The Wall at the Badlands a few weeks ago. Fella had a commercial bus that was modified to be a coach. One baggage compartment on the coach had a mini split in it. He was up working on his panels when I drove by on my e bike.

I thought it was a good setup. I'm currently back to installing the mini split on my truck camper and the roof air is being removed.
 
Highway 86 in CA on a big weekend you will see people running 80mph all day long. Im always surprised how stable they look. Might also come down to the driver. If your hobby and all the money you make goes to driving toys, good chance you are decent at driving a trailer.

Ive encountered the opposite. Old couple in an RV. 2 lane highway. The guy swerves into the dirt shoulder and kicks up a 2 inch rock that lands on my windshield. I ducked. Swing a u turn and chase the old guy down. In the process i see him swinging into the dirt shoulder multiple times. Got beside him and eventually he pulled over. They called the cops on me. CHP shows up. Tells us to go on our way. Was lame though. He was not responsible for the 2 inch rock that was imbedded in my windshield. The rock was literally stuck halfway inside and halfway outside. I know glass shards hit me and the 3 kids behind me. I was ready to pull the driver out his rig. Once i saw it was an older guy i realized its just super dangerous. He looked in a daze and his wife looked concerned as well. She is probably scared for her life as they swerve down a 2 lane highway. Hitting the loose dirt shoulder. Its the road leading CA people to the river. Lots of accidents on that highway.

Yeah it probably was a good setup but I didn't want to lose any bay space as we use the coach to carry all kinds of cargo. With my current ACs I have over 80k BTU and evenly spread out every 6ft or so. I don't know if there's any difference in efficiency with a mini split over multiple ac's considering instead of mine being adjustable I can turn separate ones on and off. Next step is to figure out the ducting and if I want it to keep ducting separate or join them somehow.

Some of my Prevost coaches have bus air which is a baggage compartment that has massive fans like a house then a huge compressor ran from the engine. Used mainly for passenger buses as they need to cool the 55 people inside but some motorhomes use them too. I didn't want because it takes up a huge bay area and only works when engines running.

Huge difference in wattage used by an air conditioning unit such as a roof air unit and an inverter mini split. I can run the roof air on my truck camper off battery for about 5 hours. An inverter mini split about 4 times that.

In a coach a multi head unit would work well, ghost flow wouldn't be as much as an issue in a house. One unit mounted to the rear of the coach or in a bay.
