Towing 5000lbs

I have a trailer that weighs about 1500lb and I have loaded it with 2000lb. I was able to easily maintain 75 to 80 mph up all hills with that combination and if I take it easy, the mileage does not go down much. This would not have the wind drag you would have with your travel trailer. To be honest, there was a LOT of power to spare. I tried this same load with a F-150 and a 5.0L and it was so under power it was dangerous. I also went down to 8 or 9 mpg with JUST the trailer on my Ford. Never mind that it also took out 3 of the u-joints!

In short, I would not hesitate to pull 5000lb with my truck even up all the hills.

I tow a 25' light TT with my 03 V6 4L 4Rnr with no problem. Weight is probably 4500# wet. I have a weight distribution hitch with antisway and, of course, electric brakes on the trailer. Have not attempted to tow it in the mountains though.

I have a 2000 Tundra w v-8 and tow a 31 foot 'light' TT that weighs proly 6200 lbs fully loaded. On straight level roads, no problems. On hills it does struggle a bit. The trailer has a hitch weight of 580 lbs (my hitch has the weight distribution and sway bars etc etc) and it does cause a fair amount of sag and makes the handling a little squirrly at times. To answer your question, I dont think you will have a problem. Im looking at upgrading the brakes, getting stiffer springs, and doing an engine chip upgrade along with headers and a cat back exhaust - but that is for my situation, which is traveling almost every weekend. Give it a go, should be fine

Another consideration is to get a 5th wheel trailer vice a tow TT. They are easier to tow and maneuver.
