The only information provided is that it's a 24' straight truck - that really tells us nothing in relation to the question you're asking. The payload it can haul is the tare weight (empty weight of the vehicle) subtracted from the Gross Vehicle Weight Rating. So, if it's a non-CDL Class 6 vehicle with a Gross Vehicle Weight Rating of 26,000 lbs. and a tare weight of 15,000 lbs., then it can haul 11,000 lbs. of payload. If it's a Class 7 truck (which does require a CDL) with a Gross Vehicle Weight Rating of 33,000 lbs., and a tare weight of 17,000 lbs., then it can haul 16,000 lbs. of payload. But without having the tare weight and Gross Vehicle Weight Rating of the vehicle you had in mind, it's impossible to tell you what you're looking for. Length doesn't determine how much weight it can haul.
That depends on what the Gross Vehicle Weight Rating of the vehicle is, and what the vehicle weighs empty (tare weight).
26000 lbs of cargo? A tandem straight truck, such as a flatbed or a dump, could haul that amount of weight legally.
Subtract the actual weight of the truck from 26,000 lbs (GVWR) to get the weight you can haul. This is assuming you are talking about a single straight truck with no trailer. It would be best to actually weigh the vehicle with full fuel tanks to get the most accurate measurement. You can get a weight at most places that sell gravel, stones, etc.
check your vehicle GVW usually listed on the door sticker. Then subtract the weight of your truck with an empty flat bed. the remainder will be what you can haul.
At U-Haul, the smallest truck that will hold 40 cubic yards (1,080 cubic feet) is a 24-foot truck. You will also need to check the weight capacity.
They're typically allowed, in the US, a gross vehicle weight of 54.000 lbs. How much that equates to in freight tonnage depends on the tare weight of the vehicle. A tandem dump truck can typically haul 15 tons. A tandem roll off with a 30 yard container is typically only good for 9 - 11 tons.
Legally, about 140 - 150% of its tare weight. Most could haul significantly more if need be.
As much as it wants
A refridgerated truck can haul 42,500-44,500lbs of good depending on how heavy the rig is. The truck can gross 80,000 total.
Negative. That IS NOT a Class 7 truck... truck classification is based on the Gross Vehicle Weight Rating, NOT the tare (empty) weight of the vehicle. That is a Class 8 truck. Other than that, it varies according to a number of factors. Wheelbase, what type of road it's on (a lot of states permit a higher weight on secondary roads), what type of axle the lift axle is (23k axle with dual tires vs. a 10k steerable pusher, etc), and so forth. What you're looking at, with that tare weight, most likely between 15 and 18 tons is what it could legally haul, depending on the above factors.

No. U-Haul doesn't rent out trucks higher than Class 6, which have a GVWR under the weight requirements for a CDL.
