i love this trailer and im not selling it..i dont gove up that easy..if i did i would have sold my truck 10 times by now
when we first got going we went about 10 miles and the trailer wouldnt go over 45 without being all ove 95...all the trailer tires i had set a 50 since thats what someone told me...we raised the air in them to 65 lb max...then the truck tires i raised to 45 insted of the 35 i had in them....on the way home i had a bogger on the drivers front and 3 samll tires on the truck with it pulled farther foward...maye a lil to far foward but none the less it pulled fine...
basically the truck needs to sit about 2 feet farther foward than it is in the pc...im thinking im gonna have to always change the rear tires and that sucks
i dont know about the tongue weight rating on the hitch but when i got a 10k trailer i put a class 5 10k hitch and got a 10k rated ball mount..IMO, way more tongue weight then you need. You practically have a whole Blazer on a hitch probably rated for maybe 750 lbs. of weight (1,000 lbs. at the most, and usually only with weight distributing hitch).
the tires om gonna try..im working on getting some wheels right now...i checked my tires and they are c rated (not good) my truck never had a rear sway bar in it...i had the same problem pulling my half naked 80 gmc, still do. try better rate tires for the sub, and make sure the trailer is inflated propertly. test pull the blazer again where it originally was. and see the result. i dont blame u about sellin the trailer to get a different ones. another thing is. when u lowered ur sub did u ever install the sway bar back in?? and i know i have seen some heavy duty trucks have a rear sway bar too.(older models) not sure. just givin some ideas out.
Oh well ok in that case fock logic...
Bro think about how valuable your time is if you have to pull the tires off every time...or if you have to keep it below 55mph OR if you have to dump more time and $$$ into this one to get it to work right...
Just because you recently bought it doesn't mean its the perfect setup for you... Its a nice trailer so if it was me I'd clean it up and sell it...then buy a longer setup. Again this is just my opinion with a little logic thrown inTake it for what it is...

Get a new trailer? Come on... There is absolutely no reason why a Blazer cant be hauled on a 20' trailer. Id bet money the issue has to do with the tires on the Suburban.well Jamie, you are right. after seeing the pics. you don't have enough tongue weight with the rear boggers on. the axles on your trailer are about centered. I bet empty the trailer pulls like crap over 55mph.
first, make sure you have max PSI in the trailer tires. C rated tires on the tow rig suck.
I'll trade issues with you any day though. I have too much tongue weight and have to use a weight distributing hitch. what really sucks is that my driveway is so bad that I have to pull out and go down the road to a flat area to hook the bars up.
sell the trailer, chalk it up as a lesson learned and buy a deckover.
..im not selling my trailer...i dont really want a deckover because of the high center of gravity..i like how they work and all the fetures of them but i still like my trailer...im gonna try a few things and get it worked out...
im thinking more and more its the c-range tires on the burb...
