Well having just slept in a RTT for the last week and being a ground/cot person, I found it interesting.
I ended up borrowing my buddies VMI Extender trailer (sweet trailer by the way) as I am currently btw contracts and waiting on the new one to start up (hopefully within a few days).
The setup for someone who has never used one, but knows all about them is super simple, I never found ground tents to be that difficult either if you buy a good quality one, I typically used exped tents and currently use a Gemini 2 with a Helinox cot and exped synmat LW for my sleep platform (I sleep very well in that setup but the tent is a bit small was bought for my adv bike days). Time to setup was slightly similar but I suspect the RTT will be faster as I didn't know where his clips/poles were and was unfamiliar with the trailer.
The size of the tent is crazy, I can fit at least a two extra people in there possibly three if they are friendly with each other and don't mind cuddling. As a single camper it was like walking into a hotel and realizing you have a king size bed to yourself.
my ground tent I'm lucky if I can get into it even though it says two man. What size man are they referring to? This man must be about 6 ft and as thin as a pencil.
The sleep quality, well I can envision with a extra foam topper to get some thickness so I am not literally sleeping on two boards would be ideal. I compare it to my days sailing on boats and those ****ty foam cushion mattresses. Not supportive and you always wake up sore no matter what size you are, just not a comfy sleep, find myself tossing and turning. I just came off a boat for a few days of sailing and it was the same there as well.
Overall, I am impressed with a RTT, with a few small tweaks (mattress mainly), so much that so that I am thinking it may meet my needs.
The draw back though is having it attached to the bed of my truck/camper. I don't want to break down the camp daily, if I am heading off to go mtb'ing, scuba diving etc, then I can't use the bed of my truck for my gear. So this puts me with a trailer mount which raises the cost of owning one drastically. Sadly I tried out a VMI, never should have as that is what I would want a trailer to be.
,
I have another 3-4 days in the RTT then I'll revise my thoughts. At the moment I'm probably 50/50.
Regards
Steve
