Moving? Drive a 26 foot Penske / Uhaul / or whatever...
Many individuals are intimidated with the large Self Load and Driving a large moving truck. They are big. They sit high. But... you tow a trailer and that is even more... difficult to master. You are already qualified and after a couple hours, you will find these large moving trucks very comfortable to travel.
My wife will even drive the 26 foot moving truck. But... I enjoy the drive. She will follow with the truck and occasionally pulling our Airstream, which is great on those two or three day hauls!
Moving heavy items into and out of the back of the truck is mostly understanding how to use a 'refrigerator dolly' with a strap... like a professional uses. Not the small two wheel dolly the company wants to rent to you. If you buy your own, it will be money well spent. The leverage and ease of moving heavy household goods is made simple.
Already understanding, at a glance, taking your tow vehicle and trailer at a fuel stop... you already have that part figured out. With 50 gallon and 70 gallon, diesel in my case, tanks... you can be patient, picking the easiest in and outs along the highway.
Don't be intimidated. Towing your Airstream takes much more skill. This transfers over to a big, loaded truck, with ease.
Negotiate down the original 'asking price'. Move when most people cannot, if you are retired. AAA, Internet ordering, mid month... all kinds of possible discounts.
Has towing your Airstream helped you do your own 'self moves'? Much like learning to ride a bicycle... you do not forget.
The money saved moving on your own... will buy lots of Airstream upgrades or tow truck fuel. Have a safe move and doing it yourself can be a lot of work... but worth it.
