I went looking for that thread hoping it might have been after the reset, but obviously it wasnt, hence this post haha.Before the great delete on GD I had posted on this and it was a lot of great info. I have a 2020 entegra accolade 37L. I love it, kids are easy to deal with, lots of room for entertaining inside. big bedroom, big shower, this is my wife's she shed so to speak. It has plenty of power and brakes to pull my 26ft box fully loaded with cars, water, fuel. I loved the dynamax and it had the bigger motor but wife liked the inside better on my seneca. We literally went to numerous dealers looking at these and we chose what we got. I dont have showhauler money but I do really enjoy my rig. I would get full air ride, nexus does not have that suspension and it really makes a big difference.
Go window shopping and see what you like.
I saw someone on gecko loop over thanksgiving with one of those f550 ones towing a stacker. Everyone I talk to say they love them. But I don’t see towing very heavy with it. Especially with how much overhang it has.I dont think I need the 20k towing capacity. I think I can get by with the 10/12k models.
What about the Dynamax Isatas or the Thor RVs on the F550 chassis. What are the verdicts on those?
I had a 2021 Thor Magnitude SV34, and overall we loved it...I dont think I need the 20k towing capacity. I think I can get by with the 10/12k models.

It was a factory F550 4x4 Chassis Cab, so 330/825 with 10-speed (2020 chassis in the 2021 coach). I kind of think Ford over-states the de-rating, or that rating is 5 minutes into a grade at WOT as it pulls boost/power because it felt just as fast up grades with my trailer behind it as my Brother-in-Law's '21 F450 with his Momentum 350G. My RV and trailer were probably 26-27k lbs combined (the RV was at every bit of the 19.5k lbs GVWR, then 7k trailer). My BIL's F450 (which has the 475/1050 HP/TQ) and his Momentum TH which would probably be about 2k lbs lighter at 24-25k lbs (~8.5k truck plus ~16k 5'er). I would NOT worry about power with these later F550-based Super Cs that have the 10 speed, at least not with anything you *should* be towing with it (aka, 10k lbs or less non-stacker).@tjZ06 Was that built on the 330hp chassis cab version of the PSD, or the 475hp like in the "regular" trucks?
I believe the 330 is pretty close. We build a machine off the F550 chassis cab. We use a system of PTOs to take power off the engine, transmission mounted and split shaft. It's calculated to be a touch over 300hp. If you look at the calculated load on a scan tool it bounces between 95-100% when we are turned all the way up.It was a factory F550 4x4 Chassis Cab, so 330/825 with 10-speed (2020 chassis in the 2021 coach).

Interesting, but awesome data to have. Either way, I did not hurt for power w/ that Thor SV34 + 24' box trailer setup.I believe the 330 is pretty close. We build a machine off the F550 chassis cab.

We have a National Security Agreement, so when we sell the equipment to the .gov we will delete the emissions. The shop that does this for us won't turn up the power on the chassis cabs. He says the turbos are smaller, and they don't handle more boost well.
The previous shop that would did this for us ONCE did turn up the boost, unbeknownst to us. This ended up superheating the charge air cooling system, and popped the coolant reservoir for it.
My old Kodiak-based super C had the LYE Duramax which was a de-tuned LMM. Rated at 330hp/620tq, it was down compared to the LBZ in my Silverado but it ran just the same towing with the Jeep on the trailer as the LBZ did towing the old 5er with same weights (about 25,500lbs combined) . I'm 99% positive that had to do with gearing as the Silverado has 3.73's and the Kodiak had 4.56 if I remember correctly. Maybe that's where the F550 makes up for the de-rated power numbers?Interesting, but awesome data to have. Either way, I did not hurt for power w/ that Thor SV34 + 24' box trailer setup.

Yeah, the F550 had 4.88s but my BIL's F450 has 4.30s, so not far behind. Both have the 10spd which as a 4.615 first.My old Kodiak-based super C had the LYE Duramax which was a de-tuned LMM.
