wind speeds

What would be maximum winds to pull 35 foot rig with 2500 Chev duramx? Winds look to be 20 to 30 on Monday.

Often you can find a detailed forecast that might let you avoid the windiest times and still get your driving done. I use a phone app called Windfinder, but there are other hourly wind forecast products from Intellicast and Accuweather. Usually it will be calmer in the morning and evening, so you may be able to drive a while early or just get on the road earlier and complete your drive before the wind gets bad.

A lot also depends upon the weight of the unit. The heavier the unit....the better it handles a cross wind. While we don’t go out looking for high winds... . we don’t panic in 30 to 40 mph. But, our unit is pushing 20K. In a light rig... I might not feel comfortable in a 20 mph cross-wind. Go slow, keep her pointed into the wind. If your “not” comfortable... park it into the wind and...”ride it out”!

We see a lot of semi roll-overs in our area....almost always an empty or lightly loaded van!

Take Bob's answer to heart. To me it also depends on the direction.

I set an all time high record this fall towing from central IL to just South of Myrtle Beach running right behind a cold front - 9.3.

Coming back was reality time - 8.7.

Just watch and see what the semi drivers are doing...if they are pulled over you might want to do the same....they are the pros.

20 or 30 with a trailer is nerve wracking for me, but I tow in it with out any problems. (And tongue weight plays a part in wind with trailers) But you're in 5th wheel and a 3/4 ton, you have lots of weight over axle for sure, 20 or 30 winds should be no problem. To me more important are the wind gusts. I haven't found a really good site yet that I like for wind or wind gusts. Keep eye out for trees or flags as you travel. See what angle they are in compared to the flag pole. I usually look (see below). On left hand side down about 1/2 way is wind and wind gusts. Believe it or not I think the wind forecasts are more accurate than temp forecasts. But very tiring driving, 1 hour feels like 3 sometimes...and keep a very close eye out for large vehicles passing on left when wind is coming from your left. The faster they get around me the better. I usually let up a gas pedal, so they get around faster. Also good sleeping weather to be rocked to sleep in RV. If its a tail wind wife loves to figure out the mileage:) My older Dodge has a wind deflector, if wind makes it bow down a bit, I know the wind is pretty strong and will slow down or stop.

For the fun of it, pull an empty set of doubles up the Columbia Gorge, inland from Portland with ice and snow in 30 or 40 mph wind. Actually not that bad once you get used to it. It's getting used to it that is the hard part.

Just don't become a member of the "interstate jack knife" club.

Looking nationally at US map in link, very few places with wind over 30.

Then there is the "live wind map" which is fun to look at.

helps to slow down a bit

5th wheels are good (maybe the best?) RV in wind. Weight centered over the rear axle of the truck, TV has a nice low center or gravity, etc. No RV is great in wind but I'd rather take my chances with a 5th and good TV than a class A or TT/truck. 25-30 MPH wouldn't make me change my plans. Much more and maybe I'd change plans.

Depends on your fear level, lol. I've towed in some pretty strong crosswinds (30-40mph) that the truck and 5th wheel took in stride.

Depends on which way the wind is hitting you. A 30 mph tailwind will do wonders for your mileage. Me, I'd wait for calmer winds.
