I had to get 32yrds of mulch and wanted to get some thing to help with my yard work so i rented a dingo witch is this. http://www.toro.com/professional/sws...400/22306.html
I also got a bed edger and that weighs like 300lbs i had a total of 2200lbs and a trailer. I have a 04 GX with towing package. I started driving and it felt like the car had no power then it was like shiming. I dont know what was amatter. Can someone tell me if they have had this problem.

 

What type of gas you running - okay, had to toss that in here with all this premium vs regular talk going on.

I've got an '05 with the tow package and have towed my trailer once thus far - 1000lbs landscaping trailer and I had it filled with landscaping rock - about 3,500lbs. So I was pulling about 4,500 lbs and noticed nothing unusual. Yes, I could feel the trailer, start and stopping take a bit longer, but nothing out of the ordinary. When the trailer is empty, I can't even tell it is back there.

But back on the gas issue, I had an X5 a while ago and was towing my loaded trailer from Sacramento to Phoenix. I did notice that after I filled up in Central California, I started getting the same type of low performance you described. Fortunately, I refueled just prior to going over the Grapevine north of LA and the problem went away - in my case, it was a tank of bad gas as it never came back.
