Picked her up today and the wife and I are happy as a clam. She towed just fine, trans temp was 185ish on the highway and 200ish in stop and go traffic. I do live in Florida and it was 85 out today when I picked it up. 200 is a little on the high side for me, so I dropped the ol' Ford off at the dealership for a trans flush and will be installing an aux trans cooler from etrailer(70 bucks is cheep trans insurance)
.
Thank you, we looked for about a year and when I saw it I knew it was the one. I plan on weighing it before we head out this weekend(if I have time) and I will post the numbers. There is a label inside that says the weight at factory as completed is 4576 pounds full with propane not including 299 pounds for water.

One caution about installing an auxiliary (oil-to-air) heat exchanger (tranny cooler). Be sure you still have adequate flow through the coolers and back into the tranny after you have the auxiliary heat exchanger installed and the ATF topped off.
Disconnect the ATF return line at the tranny and aim it at a clean container. Start the engine and let it idle for exactly 15 seconds, then move the flow of ATF into another clean container while you (or your helper) kill the engine. Then measure the volume of ATF in the first clean container. If it's not at least the minimum volume required by the tranny spec, then you have too much restriction in the tranny cooler system. A kinked line, a bad connection, or maybe just too much restriction in the cooler you installed.
I don't know the specs for your tranny, but on my F-250 with 4R100 tranny it was a minimum of one quart per 15 seconds = one gallon per minute (one GPM). Less ATF flow than the spec requires can result in a melted tranny.
Thank you for the heads up, I did not install a bigger cooler yet after reading this post. We hit the road this past weekend and she did better than expected, 180 trans temp cruising along at 55-60 at about 2k rpm highway with OD off and 195-205 in the city stop and go traffic. So if anything maybe a 5.4 cooler if I start having a temp issue. But like everyone said, shes not a speed demon but gets the job done.
I did not have time to hit a weight station, was running late to get the good spots.
