Just a couple of questions:
What is your tow vehicle and what was included in the the tow package you had installed?
In what area of northern Colorado are you picking up the trailer and what route are you planning to take on your return to NM?
Is your new Scamp
a 13' or 16' and does it have brakes
? Was a brake controller installed as part of your tow package? If you have an automatic transmission do you have a transmission cooler?
Now for the advice:
Take it slow. If you are taking I-25 to NM don't try to do the speed limit. Sixty mph is just fine. Plan your route to avoid any high mountain passes if possible. Save the up down twisty turny trip for later when you have some experience towing the trailer.
Before you get out on the open highway set up the brake controller. It is best to do this in a large empty parking lot.
Check weight/balance. Tongue weight
is very important. If it is too light
you will have sway issues. Also make sure the trailer is either level or slightly lower at the hitch. Towing with the tongue high can also cause sway at highway speeds and can cause braking issues.
I live in the Denver metro area. If you are picking up the Scamp
near here I could help you with the initial setup/hookup.
BTW - Congratulations on getting your first fiberglass camper as a gift. I'm sure you will enjoy beginning your camping experience in class with glass.
