This thread is timely as I popped in shortly after working on my
Design Your Own Sportsmobile on their website. I love my current SMB RB50 penthouse and have used it over the past 8 years as a daily driver, for camping and road trips. Over the years I've learned what I need and don't need for this point in my life. My main desire for another SMB design is #1 ~ A shower #2 ~ A permanent hightop.
I want to go "part timing" more often (3-6 weeks at a time), taking one dog and leaving hubby at home (he still works and I am retired). Though I don't really mind campground showers, I no longer want to be limited to them. And I want to do a little dry camping ... so want the convenience of everything I need being inside and onboard. Pit/sponge baths are not my thing - even a little trickle shower is preferable to me.
My 24" x 39" shower design won't have a sink or fixed toilet. I use a Luggable Loo which sits in an ottoman that also holds all related supplies. Yes, I am a bucket user as one person said

, but I prefer that to the PP. And looking for bathrooms whilst on the road is not an option for this gal with a tiny bladder. Folks that can 'hold on' while finding adequate facilities are at a stage in their life that I have
long passed. I often just pull over to a private area when needed and use my onboard potty.
My new shower design will also work as extra storage - it will hold my Loo, a removable hanging rack for overflow clothes or coats and possibly a small portable washing machine (Panda, Wonder Wash, etc). All those items will be easily pulled out when showering. Without a fixed sink and toilet, it will be a tad more spacious when showering and for storage. Anyway, that's the plan. I plan to meet with SMB this summer to go over the total design to build next year in the new Ford Transit.
We all have our camping and travel styles. Thank goodness Sportsmobile can give us what we want to meet our goals!
