Anyone with experience towing with a Suburban

Thanks again for all the excellent advice. I don't know when the rear axle last had an oil change, I didn't pay too much attention to that, but I will do it now with 75w90 and install an extra capacity cover. The transmission had the fluid changed 20,000 miles ago at an independent garage, I'll get it flushed and changed to Dexron IV fluid before we leave on the big trip in July. I'll also get one of those bluetooth senders for the OBD system to monitor transmission temp. I need to spend some time looking into the right hitch and sway control. For picking up the travel trailer my friend has offered to do it with his brand new F-250, so I'll have time to adjust the hitch and get it all set up right before going on any trips, there are CAT scales 2 miles from my house. I'm going to have another look at the trailers and discuss it with my wife. I really like the idea of the 29 foot for space, but of course the 25 foot is better for towing. Our plan is to stay at campgrounds with hook-ups for most of this year.
