unless you got 4.10 gears it should have no problem making it up to 100mph. my truck with smaller tires and 3.23 gears has made it there with room to go faster if i had space to do so legally. the speedo's go up to 180km/h here and i think my truck could do it if there was a place where it was legally allowed. you can always guess the weight and top speed for now and update them with more accurate ones later once you have had a chance to drive accross the scales. usually places like dumps or scrap yards have scales. also the od truck inspection station have them and they are always on so you can drive accross them and see the truck weight.
My truck has 235/85 tires with 16in rims, those with 8 lug nuts and top speed on speedo is 85 mph or 137km/h. I assume you have 15in rims? With smaller tires, 3.23 gears, so I guess I have 4.10 gears. Then i assume the top speed of 88mph, which I found, could be right.
Where are you located? I'm assuming the EU. I used to have a W150 similar to your truck. I kept it in good mechanical shape but the fastest I ever had it was about 82. It might have had more in it but it was an ....interesting ride. Keep in mind, when you see a listing for curb weight, that does not include fluids like fuel.
I found an old technical book. For a 4X4 version of your truck, the shipping weight is 4155 lbs,(1885 kg) and the GVW is 6900 lbs (3129 kg) A 2wd version might be about 500 pounds (226 kg) lighter without the transfer case and front differential. However, that is just a guess. I have tech books somewhere that list the 2wd trucks but finding them might take a bit.
Yes, form EU, Czech Republic exactly.
I though the curb weight is with full fuel tank. At least, we have it like that in here. So I'll keep it in mind, thank you.
It seems a lot of you guess it weights about 4000lbs, and was also my rough guess. I think I'll just go with it and I'll write it down as the curb weight.
There may be one or two metal tags on the bolts on the differential. As old as your truck is, they may have rusted away or been removed and not put back. If they are there, one might tell you the gear ratio. If you see one with two numbers, that's the ratio. 3.5 would be 3.55, 3.7, 3.73, 4.1, 4.11 gears. You can always pull the rear cover to change the oil and count the teeth on the ring gear. You can also find the number on the ring gear. Both of those can be referenced to find the ratio. You can also see if you have the sur-grip rear end.

235/75R15 is what is on mine. it is possible that your truck may be able to go faster than the speedometer can go. i know my elcamino was that way when i got it. could max out the speedo and it could still go faster and it had tinier tires than my truck. as far as the top speed question goes if your speedo goes to 85mph then that is what you tell the government. like i said the person behind the desk likely doesn't usually care what you put as long as it is within reason.
I have a 1987 Dodge W250. The attached door sticker picture, speedometer picture and a tag showing gear ratio on the rear axle may help. It has a 318 engine and 4 speed manual transmission.
