I am currently trying to decide between going with 40k rears(super 40s) keeping low air leaf suspension with a small pusher, 13.2 front air bag ride or air trac suspension 46k rears 14.6 front and a small tire pusher . I have spoken with to different sales representatives and have gotten to different answers. 1 recommends the 1st set up S.R. #2 suggested the 2nd option
The truck will be double framed I will be able to gross up to 120k now pulling a 3axle step now and will be getting into some 4 axle rgn work in the future grossing 140-146k max
With that being said I’m trying to set myself up to be able to use both trailers without giving or taking so much from one or the other if possible
The truck will have a 310wb sales rep 1 says that even with rgn work there is no way I’ll be able to get that much weight on my steers and that the 14.6 fronts will be unesserary even with the rgn. Also that air trac rides like #### and that I will be a lot happier with the low air leaf suspension.also that there is a good bit of weight added by going 46k rears and full lockers ... and that I can make it work with the 40s and 13.2 fronts
Sales rep 2: advice given was that it would be cheaper to get the the heavy duty setup from factory vs having to swap later if needed. And simply that i would hate to miss out on loads from not being able to handle the weight
I have not done any rgn work yet so I really don’t know what I can get by with. Also the rgn setup I am looking at i won’t be adding to my operation right away it will be a couple years atleast
Looking for real world experience and advice

388 or short hood 389, 312"wb, frame insert from rear of frame to back of cab, 14.6 front, 13.2 lift, ds40-170 rears on low air leaf, 54" drive spacing, 90" from front driver to lift, 60" slider on my 5th wheel with its rear centerline set at the center of the tandems. Gross 105,500 on a daily basis in the northwest. 13-14.6 with the lift down while loaded. With our trailers I often see 17,000 on the steers before dropping the lift so you're salesman stating you cant get the weight up front is full of BS and you should not give him a second chance on spec'ing your truck. I would call around to other dealers and ask if they spec many HH rigs or just call up one in the states that higher weights and 4 axle tractors are a common thing.
