If you can stay under 7000# you should be ok. I pull a 27' that weighs 6500 - 7000 ready to camp full water. I pull it with a 1500 GMC 4x4 crew cab with a 5.3 and 342 gears. it tows absolutely perfect. I've been to Alaska and east to Wyoming and haven't found a hill I can't go up at 65mph, most I could do 80 if I wanted to. length should be ok also, we came back through Idaho and hit a 30 to probably 40 mph side wind for about 300 miles the trailer moved a little but nothing unmanageable. it actually handled the wind better than I thought it would. i wouldn't go much over 7000 if you can and as far as tongue weight you might have to watch how you load the trailer.

What year Silverado do you have. That can make a big difference.Older ones had 295 HO or 315 HP with either 4spd or 6 spd trannys. My 2017 has 355 HP and the 8 spd. It tows our 31 ft with no problems It also has payload of 1940 lb so it can handle the tongue weight fine. Our 2012 with the 6 spd was OK but the engine ended up at higher revs on long 6% grades.


Yeah mine is a 2017 as well. Any experience with pulling it up and down mountains?

Have seen this formula for length, pretty sure there's some science behind it but wasn't quoted: "Rule of thumb (20’ for 110” wheelbase + 1’ for each additional 4” of wheelbase)"

That was adopted (plagiarized) from a veteran RVer on this forum. With this formula, my previous GMC 1500 was right at the safe limit of (27.9' calculated) and my RV is 28' hitch to bumper.

For what it's worth.

Yeah I saw the same thing. This one is 143.5 so probably the same as your GMC. I didn't know if that length would be a major difference or not. I was worried about the weight going up the hill. I know the tow capacity says 9100 but I figured it wasn't wise to be close to the max. Of course the dealer says "you're good! You have almost 3,000lbs to spare between dry weight and towing capacity." Thankfully I'm knowledgeable enough to know better

could likely be done, I wouldn't. not going to be a fun tow. whats the payload of the chevy?

payload minus weight of everything and everyone in the truck and truck bed minus 100 lbs for the wd hitch is whats left for tongue weight.

take that number (the remaining payload) and multiply by divide by 0.15 and that's the heaviest I would tow.

dry weight means nothing. use the gvwr.

example for my f150

1850
-400 (family and this will get bigger my kids are little)
-250 (stuff in truck)
-100 (hitch)
-100 (fluff since I like to have room)
=1000 available tongue weight

1000/0.15=6667 lbs
my camper comes in fully loaded rate around 4500(shes only 23 feet and the and tows wonderfully gvwr 4677)

go


If it moves and it shouldn't..... duct tape
if it doesn't move and it should.....WD40
if all else fails .....BFH

^side tip when figuring out what your family weighs, take 40 lbs off the wife and tack it on yourself. this will make for a better trip. trust me.

You need a bigger truck. Never tow with something that is "Just on the line". Remember it's not all about towing. At some point you may have to stop that rig suddenly. That's a bad time time to realize you needed a bigger truck.

And if you are silly enough to buy clothes for her make sure the top is too big, and the pants to small

The payload is 2180. So based on those calculations I'd have about 1180 available time tongue weight and 7800 for camper weight. So by the time the camper is loaded with stuff I'm sure it will be closer to 6700-7000lbs. So would be close. Like you said then. Could probably be done but wouldn't be great towing.
