Thank you all for the responses. This is what I had thought. I had rose colored glasses on. As I mentioned the van was given to me from my father. When I got it he said it was the best tire vehicle he ever had no problems towed his TT (the one I grew up with) and fully packed was close to 10,000. Well I came to find out his that (by asking Mom) that trailer dry weighed 5,100lbs and fully loaded was only 6,600lbs. I love my Dad but always go to Mom for the full story.
So I forgot to mention the clutch fan was replaced during the work on the van, it wasn't fully engaging. It definitely roars when it kicks in. The torque was replaced each time the tranny was replaced and locks up when driving. When I tow I keep the overdrive off.
After the first tranny went I had installed a tach and a tranny temp gauge. This is how I knew I was running hot. Per Jasper (the tranny remanufactured) they don't send the tranny fluid through the radiator. Apparently the 94 fired tranny lines in the radiator were to small. Luckily due to the warranty Jasper replaced the tranny and provided a much larger cooler. This new cooler send to be keeping the tranny temp down about 30 degrees which fit me is comforting temps in the 160 no load and 190 with load.
The last tow I did not long about 30 mile tow the tranny never went over 160. I took note of the following. The TV runs at about 2800 rpm with overdrive off no trailer and runs about 3000 with overdrive off with the trailer at 65. The only difference is how far I am pressing the gas peddle. Without the trailer I have a long way to go with the trailer there is little left. I did try to advance the timing by the degrees, this didn't seem to give me any more power but it did make the engine run a little hotter. I will be seeing the timing back.
This was all really helpful and brings my expectations to where should be.
Next year I am planning on taking a 1,500 mike trip this set should be ok right? Or do I need to consider a different TV I hope not.
