Thanks guys for the response's back. KcStudly and jss06 your guys build have gave me alot of good ideas. I plan on not having wheel wells. Trying to keep a full mattress for me and squeeze my little boys in it. I am going to keep with the leaf springs at this time i decided in a spoa setup with about 1.5" space between the tire and camper body. Now let me run some numbers by you guys and make sure i have this right before I order a axle lol.
Hummer truck measurements with 35" tires
outside springs/frame to outside spring/frame = 44.5"
distance from inside tire to inside tire 52"
distance from tire to leaf spring 4"
Sooo If I'm going to build a 58" wide trailer to fit a 54" full mattress (accounting for walls and insulation 2" per side)
44.5" + 13.5 = 58 so the outside of my leaf spring will be at 58"
Take my WMS of 68+13.5 = 81.5" now I have 4" each side from tire to frame/spring and if i set a 1.5" gap from frame to tire I would subtract 5" more from the overall WMS 81.5"- 5" = 76.5 round up for fun and i need a trailer axle with a WMS of 77"??????
lol in flaws in my math or should i have had one less beer tonight?
