A "2007 23 ft. Ameri Lite travel trailer that weighs about 4000 lbs." is likely a 23BW at 7.5'W x 9.5'H which I guess compared to some might be considered a smaller lower profile trailer. Since that's what the OP is asking about towing specifically, I'll offer advice on that and refrain from suggesting another $30-$50K for a replacement trailer too.Hmmm. No. Getting past the budget thing, an electric truck like the Rivian or Ford would easily pull a smaller lower profile tailer twice as far as you indicated. The electric Silverado would easily pull it 250 miles or more.
I actually did assume twice the radius I suggested assuming at some point they might want to go home and possibly not remain parked the duration of camping. Will they be at a campground that prohibits electric vehicle charging? Want to find out after you're already there? How far away is a charging station; 5 minutes, 90 minutes? I can add 400 miles of range to my minivan in ~3 minutes counting the time to fart around with my wallet and the pump, about double that time for my truck. I see this as a convenience, some may see adding that range in 1-3 hours (with multiple stops) to be a feature rather than a drawback, just depends on what flavor of propaganda you prefer.
