Over the 4th of July weekend, we went on a glamping trip to Taylor Park for some water sports and biking. Towing a 3,500 lb camper and a few hundred pounds of gear and people, the truck handled beautifully. Charged in salida on the way out. This is a bit out of the way but we took advantage of the grocery store next door to get supplies for the trip. Went over cottonwood pass (over 12,000ft elevation) without breaking a sweat and arrived at the campsite (Lakeview Gunnison) with just over 50%. During our stay, we did some driving back and forth to the lake and a little light off-roading. There is a forest service L2 charger at the marina which we weren’t counting on, but took advantage of as it was available, free, and outputting just over 7kW (thank you forest service!).

Using the truck to power our cooking equipment is a huge plus for us. The induction stove and electric kettle are much quicker than propane and we can save the propane for heating the camper at night (nighttime temps dropped to lower 40s F up there).

We returned via FairPlay stopping just briefly at the ChargePoint there. We didn’t have to wait and didn’t have to unhook either time so I count that as a win.

I didn’t separate the trip meter on the two legs so I can only report the average over the trip. We encountered strong cross winds on the outbound and headwinds on the way back so that dropped the efficiency. I do not think that the kayak on the roof made much of a difference as we would have been pushing that air anyway with the camper.

That looks like a pretty good result considering all the gear, people and trailer. We're getting around 1.4-1.6 efficiency with our setup, but we have the 20" tires, which, from what I'm seeing, makes quite a bit of difference. As expected, speed has the greatest impact on efficiency for us. This is our setup...

Good to hear about your results. Wife and I have a happier breeze model on order so should get slightly better results on efficiency. Little bit smaller than yours and lighter. Excited for later this summer once it gets delivered after their factory delay.

Cool rig! What camper is that? Yes, I suspect that with different tires you might eke out a bit more. That said, anything above 1.5mi/kWh is pretty good for pulling a little home on wheels!

Cool, is it the traveler breeze or HC1 (the one with the hatch)? Either way, wish you many fun adventures with it and looking forward to comparing notes!

It's the hc1 breeze. Replacing a hiker trailer 5x9 mid range which was a little small with the two dogs.

Interesting side note #1: I did not get any regen limiting going westward over the pass but did get about 2/3 limiting on the return of the same pass, with the limiting kicking in almost immediately on the downhill. The only difference is that the westward leg followed a RAN charging session and may have been at slightly cooler ambient temps. With the battery having just preconditioned and the BMs activated, perhaps the battery was still cool enough to not limit regen?

Great! And we both have 21’s so we could do a direct comparison. We really wanted to get an HC1 and loved the hatch design but needed the room for two kids and us to fit reasonably. Even with the bunk-bed it would have been a squeeze. Ended up finding a used traveler in fair condition so that sealed the deal.

It's an Aliner AMP. Nearly all electric with 800W solar and EcoFlow Power Kit with 5kW LFP battery. So far we really like it.

I've noticed that, but I think more related to what your state-of-charge was. I've gone down a 3,500 ft pass here in BC with no limiting because I started at the top around 30% or so (IIRC).

Good point. I may have been upper 40% to low 50% descending on the way out and upper 50% to lower 60% when starting the return descent. So I may have crossed some threshold…

A friend of mine is selling their off road teardrop. These are also super efficient.

Always impressed with your TrailManor posts given how large it is. It’s the transformer of campers.

Interesting note #2: passed about 4-6 Rivians each way and almost all gave me a wave and or brights flash. If you’re on here, thanks!
